OPINION
A North Carolina jury convicted John Hardy Rose of capital murder for the murder of Patricia Stewart. Following a capital sentencing proceeding, the jury recommended, and the trial court imposed, a sentence of death. After exhausting all available state remedies, Rose petitioned the United States District Court for the Western District of North Carolina for a writ of habeas corpus. See 28 U.S.C.A. § 2254 (West Supp.2000). The district court ordered that the writ be granted on the ground that the State habeas court applied the wrong legal standard to Rose’s ineffective assistance of counsel claim. The remaining allegations in Rose’s habeas petition were dismissed.
Rose seeks a certificate of appealability granting permission to appeal the portion of the district court’s order denying Rose’s habeas relief. The State cross-appeals the *681 portion of the district court’s judgment in which the district court granted the writ and remanded to the State habeas court for its application of the proper legal standard to Rose’s ineffective assistance of counsel claim. 1 For the reasons that follow, we reverse the portion of the district court’s judgment granting the writ, affirm the district court’s entry of summary judgment in favor of the State as to Rose’s claims, and decline to grant Rose a certificate of appealability.
I.
A.
After receiving a report that Patricia Stewart was missing and finding small drops of blood in and around her apartment, the Graham County, North Carolina, police department conducted several interviews with Rose, who lived with his sister and her boyfriend in the apartment above Stewart. 2 On January 13, 1991, State Bureau of Investigation (SBI) Agent Mark Nelson performed a consent search of a blue Pontiac owned by Rose and a yellow Ford owned by his sister. In the two cars, investigators found a pair of numchucks, a tire tool, jumper cables, a black sleeveless jacket, and a thermos, all of which tested positive for blood. The thermos and the trunk of the Ford contained bloodstains that were consistent with Stewart’s blood type and inconsistent with Rose’s.
On January 14, SBI Agent Frye met with Rose to discuss the results of the searches of the two automobiles. Rose told Frye that he did not want to discuss Stewart’s disappearance “because the situation surrounding it was too bad to talk about, and he was concerned about what his family would think of him.”
State v. Rose,
On January 15, agents spoke again with Rose, this time in the presence of his mother. Rose’s mother told Rose that he needed to reveal any information he had regarding Stewart’s disappearance. Rose informed the agents that Stewart’s body was located at his grandmother’s farm. Agents radioed this information to officers searching for the victim’s body, who in turn informed the agents that the body had already been uncovered.
Rose then was arrested and given
Miranda
warnings for the first time.
Miranda v. Arizona,
*682 Rose then wrapped Stewart’s body in her bed linen and put it in the trunk of his Pontiac, but the car would not start. Rose stated that he then went back inside and tried to clean up, leaving Stewart in the trunk. He took the knife that he used to kill Stewart to his apartment, cleaned it, and placed it in a box in his bedroom. The next evening, Rose borrowed his sister’s Ford automobile and transferred the body to the trunk of the Ford. He drove the Ford to his grandmother’s farm, took the body behind the house, used his grandmother’s hoe to dig a shallow grave, poured gasoline on the body, set it afire, and walked away. When the fire went out, Rose returned and covered the body with rocks, leaves, and tree branches.
Rose’s testimony during the guilt phase of the trial was similar to his confession, with a few deviations. Rose testified that after he told Stewart he was going to Alabama, Stewart reached over and picked up a pocket knife that she had lying on her nightstand beside her bed. Rose claimed that Stewart shook the knife and said, “You ain’t going nowhere.” Id. at 526. Rose testified that he jumped up and hit Stewart’s arm, causing the knife to hit her in the head, and immediately jumped on top of her. Rose testified that he then “heard something pop, backed up and saw blood coming out of Stewart’s head.” Id. Rose testified that “he did not remember choking Stewart that morning and that he did not intend to harm her and did not think anything like that would happen.” Id.
A medical examiner testified that Rose stabbed Stewart five times, with four knife wounds to her body and one knife wound to her head that was inflicted with enough force to pierce her skull. Id. at 532.
B.
The jury returned a verdict finding Rose guilty of first-degree murder. Following the return of the guilty verdict, a capital sentencing proceeding was held pursuant to N.C.Gen.Stat. § 15A-2000 (1999). At sentencing, the State introduced as aggravating evidence exhibits related to Rose’s conviction in Mississippi for attempted rape.
See Rose,
On May 12, 1992, Rose appealed to the North Carolina Supreme Court, which unanimously found no error in Rose’s conviction or death sentence. On June 27, 1994, the United States Supreme Court denied Rose’s petition for a writ of certio-rari. Rose filed a petition for state habeas corpus relief, which is termed a Motion for Appropriate Relief (“MAR”) in North Carolina. After holding an evidentiary hearing, the state habeas court denied Rose’s requested relief.
Rose then petitioned the federal district court for habeas relief, challenging his conviction and sentence on numerous grounds. The petition was referred to a United States Magistrate Judge, who recom *683 mended that the district court dismiss on summary judgment the majority of Rose’s claims but grant the writ with respect to Rose’s ineffective assistance of counsel claim.
After a de novo review, the district court agreed with the magistrate judge’s recommendation and issued a writ of habeas corpus with respect to Rose’s ineffective assistance of counsel claim but dismissed Rose’s habeas petition with respect to Rose’s remaining claims. The district court remanded the ineffective assistance of counsel claim to the state habeas court to determine whether Rose can establish his claim under the governing legal standard set forth in
Strickland v. Washing
ton,
Rose seeks to appeal three issues upon which the district court entered summary judgment in favor of the State: (1) whether his confession was illegally obtained; (2) whether the imposition of the death penalty in North Carolina unconstitutionally discriminates against the impoverished; and (3) whether the ex post facto clause bars the application of N.C.Gen.Stat. § ISA-1419 to his habeas petition. We will address each of Rose’s arguments and then turn to the State’s argument that the district court erred by remanding the ineffective assistance claim to the state habeas court for application of the proper legal standard. 3
II.
To be entitled to a certificate of appealability, Rose must make “a substantial showing of the denial of a constitutional right.” 28 U.S.C.A. § 2253(c)(2) (West Supp.2000). In
Slack v. McDaniel,
A. ROSE’S EX POST FACTO CLAIM
Rose filed his MAR on October 4, 1995. On June 21, 1996, the North Carolina legislature amended N.C.Gen.Stat. § ISA-1419 (1999 & Supp.2000), which addresses default of claims on state collateral review. Prior to this amendment, the procedural bars established under § 15A-1419 were discretionary. The amendment makes the procedural bars found therein mandatory rather than discretionary, unless the petitioner can establish good cause or that the failure to consider the claim will result in a fundamental miscarriage of justice. N.C.Gen.Stat. § 15A-1419(b). 4
The State habeas court applied the amended version of § 15A-1419 to several of Rose’s claims and held the claims procedurally barred. Rose argues that the application of § 15A-1419 as amended violates the Ex Post Facto Clause of the United States Constitution. U.S. Const, art. 1, § 9, cl. 3. The district court rejected this claim on the merits. Because the district court rejected the Ex Post Facto claim on its merits, Rose must demonstrate that reasonable jurists would find
*684
the district court’s assessment of the constitutional claims debatable or wrong.
See Slack,
The Supreme Court has recognized four categories of Ex Post Facto criminal laws.
Carmell v. Texas,
Retroactive application of a procedural law such as § 15A-1419 can violate the Ex Post Facto Clause, but only when the procedural law falls within one of the above four categories.
See Collins,
The amendment to § 15A-1419 making the procedural bars mandatory rather than discretionary does not alter the definition of the crime of first degree murder, of which Rose was convicted, nor does it change his available defenses to the crime of murder or otherwise increase the punishment for which he is eligible as a result of that conviction. Similarly, the amendment does not alter a legal rule of evidence in a manner that requires less evidence to support a conviction. While it is true that the amendment to the procedural bar provision worked to Rose’s disadvantage, the Supreme Court explicitly has held that a law does not violate the Ex Post Facto Clause simply because it “alters the situation of a party to his disadvantage.”
Collins,
B. PROCEDURALLY DEFAULTED CLAIMS
Rose seeks to appeal the district court’s denial of several claims pursuant to the district court’s finding that the claims were procedurally defaulted. As established in
Slack,
to secure a certificate of appealability on claims that the district court denied pursuant to procedural grounds, Rose must demonstrate both (l)“that jurists of reason would find it debatable whether the petition states a valid claim of the denial of a constitutional right” and (2)“that jurists of reason would find it debatable whether the district court was correct in its procedural ruling.”
*685
Slack,
1. Rose’s Confession
Rose first seeks to appeal the district court’s denial of his claim that his confession was unconstitutionally compelled with a promise of life imprisonment and then used to secure his death sentence. The district court found that Rose’s illegally obtained confession claim was proeedurally defaulted for purposes of federal habeas review because the State habeas court determined that it was proeedurally barred pursuant to N.C.Gen.Stat. § 15A-1419(a)(2) (1996).
5
To determine whether Rose is entitled to a certificate of appeala-bility on his confession claim, we first address “whether jurists of reason would find it debatable whether the petition states a valid claim of the denial of a constitutional right.”
Slack,
Before the State habeas court, Rose submitted affidavits from his mother and sister, both dated January 6, 1998,' averring that on January 15, 1991, an agent told them and Rose directly that “things would go easier on [Rose] if he told them where the body was.”
6
(J.A. at 769.) The State habeas court noted that the allegations contained in the affidavits were presented and considered on direct appeal. As Rose’s counsel acknowledged at oral argument, Rose’s claim is not one premised upon an alleged violation of
Miranda v. Arizona,
We measure whether a confession was unconstitutionally coerced by the totality of the circumstances.
See Arizona v. Fulminante,
Moreover, the circumstances surrounding the confession are replete with indicia of voluntariness. As the State court noted on direct appeal, the evidence shows that Rose voluntarily agreed to talk with law enforcement officers at every juncture leading up to his confession.
State v. Rose,
2. Discrimination Claim
Rose next seeks to appeal the district court’s denial of Rose’s claim that North Carolina unconstitutionally discriminates based upon economics in its imposi *687 tion of the death penalty. Rose argues that North Carolina imposes the death penalty only upon poor people, in violation of the Fifth and Fourteenth Amendments of the United States Constitution. The district court declined to address the merits of Rose’s economic discrimination claim because Rose failed to “fairly present” the issue to the State courts; thus, the district court held the claim procedurally barred. (J.A. at 18-19.)
In his Reply Brief, Rose admits that his economic discrimination claim was not presented to the State courts, although he did present a racial discrimination claim.
8
Because Rose concedes that he did not present his economic discrimination claim to the North Carolina courts, we are precluded from addressing the merits of this claim unless Rose demonstrates cause for his state-court default and prejudice resulting therefrom.
Edwards v. Carpenter,
On appeal, Rose argues that he has established sufficient cause to overcome the procedural default of his claim, claiming that the facts underlying the economic discrimination claim were not readily available to Rose’s counsel during the State proceedings. Initially, we note that the record does not reflect that Rose presented any argument with respect to cause before the district court. (J.A. at 19) (stating that “[n]owhere does Petitioner show cause as to why he did not raise his economic discrimination claim in State court”). Thus, Rose’s cause argument is deemed waived for purposes of this appeal.
See Skipper v. French,
Assuming, however, that Rose raised his cause argument below, we find it inadequate to overcome the procedural default. It is true that a petitioner can establish cause by showing “that the factual basis for [the] claim was unavailable to him at the time he filed his state habeas petition.”
Breard v. Pruett,
The statistics underlying the economic discrimination claim were available to Rose’s counsel upon a reasonably diligent search.
10
Counsel’s failure to consid
*688
er the argument is insufficient to constitute cause.
See Murray v. Carrier, 477
U.S. 478, 488,
No appeal is warranted when “a plain procedural bar is present and the district court is correct to invoke it” to dispose of a claim.
Slack,
III.
Having determined that Rose is not entitled to a certificate of appealability on the issues raised in his appeal, we next address the State’s argument that the district court erred by granting a writ of habeas corpus with respect to Rose’s ineffective assistance of counsel claim. The parties agree that the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA), Pub.L. No. 104-132, 110 Stat.' 1214, governs our review of this issue. Pursuant to that statute, a federal court may not grant a writ of habeas corpus with respect to a claim adjudicated on the merits in a state court proceeding unless the state court’s adjudication: (1) “resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States,” 28 U.S.C.A § 2254(d)(1) (West Supp.2000); or (2) “resulted in a decision that was based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.” Id. at § 2254(d)(2).
The district court held that the State habeas court rendered its decision in a manner contrary to clearly established law when it denied Rose’s ineffective assistance of counsel claim pursuant to the wrong burden of proof. Although the district court noted that Rose’s ineffective assistance of counsel claim is meritless, the district court held that it could not independently reassess Rose’s ineffective assistance of counsel claim according to the proper standard; instead, the district court “remanded” 11 the claim to the State habeas court. While we agree that the State habeas court applied the wrong burden of proof to Rose’s ineffective assistance claim, we disagree with the district court’s conclusion that a federal court lacks authority to conduct an independent review of the claim.
A.
Initially, we note that “clearly established” Supreme Court precedent governs Rose’s ineffective assistance of counsel claim.
Williams v. Taylor,
*689 First, the defendant must show that counsel’s performance was deficient. This requires showing that counsel made errors so serious that counsel was not functioning as the “counsel” guaranteed the defendant by the Sixth Amendment. Second, the defendant must show that the deficient performance prejudiced the defense. This requires showing that counsel’s errors were so serious as to deprive the defendant of a fair trial, a trial whose result is reliable.
Id.
at 687,
B.
We next address whether the State habeas court’s ruling was “contrary to” the
Strickland
test.
Williams,
If a state court were to reject a prisoner’s claim of ineffective assistance of counsel on the grounds that the prisoner had not established by a preponderance of the evidence that the result of his criminal proceeding would have been different, that decision would be “diametrically different,” “opposite in character or nature,” and “mutually opposed” to our clearly established precedent because we held in Strickland that the prisoner need only demonstrate a “reasonable probability that ... the result of the proceeding would have been different.”
Williams,
C.
Upon recognizing that the State habeas court’s adjudication of Rose’s ineffective assistance claim was contrary to clearly established law, the district court held that it lacked the authority to conduct a de novo review of Rose’s ineffective assistance claim using the proper legal standard under
Strickland.
In coming to this conclusion, the district court relied upon the magistrate judge’s recommendation that
Williams
bars harmless error review of ineffective assistance claims. Of course, we agree with the district court that, if Rose was denied the effective assistance of counsel, the error would not be subject to harmless error review.
Williams,
In
Williams,
as in this case, the state court erred in its framing of the applicable legal standard under the controlling Supreme Court precedent of
Strickland. See Williams,
Our authority and obligation to conduct an independent review of the substantive constitutional claim is firmly rooted in the underlying purpose of the writ of habeas corpus, which is to ensure that prisoners are not held in custody “in violation of the Constitution or laws or treaties of the United States.” 28 U.S.C.A. § 2254(a). As the
Williams
Court noted, the writ of habeas corpus is not designed to correct all constitutional errors, much less all errors of any kind.
See Williams,
As Rose concedes, the facts related to his ineffective assistance of counsel claim have been fully developed by the State habeas court pursuant to a four-day evi-dentiary hearing, during which five witnesses testified and several affidavits were introduced, and the State habeas court resolved all credibility determinations related to Rose’s ineffective assistance of counsel claim. Despite Rose’s concession, he contends that issuance of a conditional writ is warranted because the State court is better suited to apply the Strickland standard to his claim, insofar as the application of the standard is a fact-intensive inquiry that depends on the subtleties between varying burdens of proof. The evidence introduced before the State habeas court, as well as the court’s factual findings and conclusions therefrom, are fully set forth in that court’s Memorandum Order and Final Opinion and, therefore, are easily accessible to this Court on review, as is the full record of Rose’s prior state proceedings. Inasmuch as the only task remaining is application of a legal standard crafted pursuant to federal law to facts that are readily available to this Court, we consider ourselves well-equipped to evaluate the merits of Rose’s ineffective assistance claim.
*691
If, after applying the
Strickland
standard to the facts developed by the State habeas court, we determine that Rose actually received effective assistance of counsel, Rose will have failed to demonstrate that constitutional error infected his trial or conviction in any way. Neither
Williams
nor § 2254(d)(1) requires issuance of a writ before determining the critical question of whether a prisoner is being held in violation of the Constitution or laws of the United States. Thus, the proper interpretation of the role of § 2254(d)(1) in habeas corpus review is that it establishes a threshold by which we determine whether we are authorized to issue a writ, but it does not compel the issuance of a writ once the standard set forth therein has been satisfied.
See id.
at 412,
IV.
Turning to the merits of Rose’s ineffective assistance of counsel claim, Rose contends that he was denied the effective assistance of counsel at his death penalty proceeding because his attorneys did not adequately investigate the events surrounding his prior violent felony attempted rape conviction that was used by the State as an aggravating factor. Had his counsel investigated the events surrounding the attempted rape conviction, Rose argues, counsel would have discovered significant mitigating evidence relating to Rose’s mental health. Specifically, Rose argues that his counsel should have requested his prison records from his prior attempted rape conviction, which contained information indicating that the prison doctors had diagnosed Rose as suffering from sexual and social disorders. Properly applying Strickland, the record supports the State habeas court’s ultimate rejection of Rose’s ineffective assistance of counsel claim.
During the evidentiary hearing before the State habeas court, Rose introduced testimony pertinent to the mitigating evidence of mental disorders that he currently says should have been introduced to the jury. Dr. Brown and Dr. Berlin, both psychiatrists, testified separately that Rose relayed to them a dramatically different story regarding Stewart’s death than Rose had relayed to his trial counsel, law enforcement officers, and the jury.
Dr. Berlin testified that Rose told him that he did not have a relationship with Stewart, but he had instead been spying on her through her window on the night of the murder. On this account, Rose waited until Stewart was asleep before entering her apartment through a window. Rose went to Stewart’s bed and stabbed Stewart, wounding but not killing her. Stewart told Rose that if he left without killing her, Rose would escape punishment because she would not be able to identify him. Rose placed Stewart’s head in his lap and strangled her with a nylon strap until he heard several “pops” and “snaps.” (J.A. at *692 76.) Rose then put her body in the trunk of his ear and violated her by inserting numchucks into her vagina. Rose then masturbated by the car’s back bumper. Rose told Dr. Berlin that he had, prior to trial, told one of his trial attorneys the truth about Stewart’s death, but the attorney dismissed it.
In addition to relaying this version of Stewart’s murder, Rose told Dr. Berlin that he had entered as many as 20 homes and stood fantasizing over the bed of the occupants, while holding a knife and having thoughts of injuring them, and on more than 100 occasions he also had entered other homes and masturbated over people’s beds. Based upon Rose’s statements and his prior conviction for attempted rape, Dr. Berlin opined that Rose had sexual disorders, voyeurism and sexual sadism, and was mentally impaired respecting his ability to conform his conduct to the requirements of law. Rose told Dr. Brown a similar story about Stewart’s murder, adding that before he assaulted Stewart’s vagina with the handles of the numchucks, he burned her vaginal area with a “pencil torch.” (J.A. at 259.)
Other evidence of Rose’s disorders included an evaluation from Dorothea Dix Hospital. Prior to trial, the trial court had ordered that Rose undergo a psychiatric evaluation at Dorothea Dix Hospital to gauge Rose’s competence to stand trial. The report issued in conjunction with that evaluation concluded that Rose suffered from a provisional sexual disorder and a mixed personality disorder, but that Rose was otherwise competent to stand trial. Rose argues that, in light of this preliminary evidence of mental disorders, his trial counsel should have further investigated and presented evidence of his disorders to the jury to support a statutory mitigating factor.
As the State habeas court noted, however, Mr. J.K. Coward, Jr., Rose’s lead trial counsel, testified that Coward and his co-counsel, Marcellus Buchanan, were fully aware of the diagnosis of the disorders in the Dorothea Dix report, but they had decided not to pursue a defense that included Rose’s sexual disorders because they felt that introducing “further bad elements into the case” would mean that they “would have no chance whatsoever with the jury.” (J.A. at 248.) Coward testified that introducing any testimony regarding Rose’s sexual disorders during the sentencing phase “would eliminate the chance for any kind of leniency.” (J.A. at 248.) Additionally, Coward and Buchanan felt constrained not to introduce evidence of Rose’s sexual disorders because Rose explicitly had instructed them not to present any evidence that would expose Rose’s children to adverse publicity.
Instead of pursuing Rose’s mental disorders as a defense or a mitigating factor, counsel attempted to avoid any of the sexual content of Stewart’s murder, which they succeeded in doing. Additionally, counsel attempted to engender sympathy for Rose by focusing on his troubled upbringing, good character, and strong work habits.
Our review of relevant excerpts from the transcript of the evidentiary hearing and the findings of the State habeas court conclusively establishes that Rose’s trial counsel acted in an objectively reasonable fashion by declining to pursue a defense based upon Rose’s sexual disorders. Rose’s trial counsel made a strategic decision to keep any evidence of Rose’s sexual disorders out of the trial because they determined that any such evidence was contrary to the express order of their client to protect his children and would decrease their chances of success.
See Turner v. Williams,
Nor has Rose established that any alleged constitutional deficiency in the performance of his counsel was prejudicial, that is, that there is a “reasonable probability” that Rose would have been spared the death penalty if his counsel had conducted more extensive investigation into his mental health. “A reasonable probability is a probability sufficient to undermine confidence in the outcome.”
Id.
at 694,
Nevertheless, Rose argues that but for his counsel’s failure to uncover additional evidence about his sexual disorders, there is a reasonable probability he would have been spared the death penalty. In support of his argument, Rose points to an affidavit of Samuel Kent Chapman, one of the jurors from Rose’s trial, which stated that, if Chapman had found that “Rose suffered from some mental health problem or disorder, [Chapman] would have voted to give him a life sentence rather than a death sentence because [he] do[es] not believe that a person who doesn’t appreciate or understand what he is doing needs to be executed.” 12 (J.A. at 477-78.)
Chapman’s affidavit is too vague to undermine our confidence in the outcome of the death penalty phase of the proceeding. Chapman’s affidavit does not indicate that he was aware of Rose’s proffered disorders *694 when he averred that a certain type of mental disorders would have influenced his decision to impose the death penalty. Rather, Chapman indicates that when a person has a mental disorder rendering him incapable of appreciating the nature of his conduct, he would be inclined to vote against the imposition of the death penalty. Rose’s evidence regarding his mental disorders does not establish that Rose was incapable of appreciating the nature of his conduct. To the contrary, Dr. Berlin opined that Rose was capable of appreciating the criminal nature of his conduct but was incapable of conforming his conduct to the requirements of the law. Similarly, Dr. Brown opined that Rose was fully able to premeditate and deliberate at the time he murdered Stewart; “he knew what he was doing and he knew it was wrong.” (J.A. at 262.) Thus, Chapman’s affidavit simply does not address whether Chapman would have voted against the death penalty if Chapman possessed full knowledge of Rose’s particular mental disorders and the alternate version of the events surrounding Stewart’s murder. Accordingly, we do not believe that Chapman’s affidavit is probative of whether Rose has demonstrated a reasonable probability that he would have received life imprisonment had the jury been presented with evidence of Rose’s particular mental disorders.
Mr. Alexander McCoy, who attempted to be certified as a “mitigation specialist,” also testified during the evidentiary hearing. The State habeas court declined to accept McCoy as an expert but accepted his testimony and opinions relating to capital trials. McCoy opined that Rose’s trial counsel erred by failing to introduce evidence to support a mental health instruction. McCoy admitted, however, that if counsel had introduced Rose’s alternative version of Stewart’s murder to the jury, it would not have been helpful and would have further supported the statutory aggravating factor. Additionally, he admitted that he knew of no ease in which evidence presented to the jury that the defendant suffered from a mental illness that caused him to want to murder, rape, and torture women was found to be persuasive in choosing life over death. (J.A. at 245.) As McCoy admits, his opinion that introduction of such evidence would have been beneficial to Rose amounts to pure speculation.
The only other evidence offered to support a finding of prejudice is that of Mr. David Belser, an attorney who testified as to the proper standard of care. Belser testified that Coward should have ignored his client’s wishes and introduced evidence of the sexual disorders. Belser further testified that there was a reasonable probability that introducing such evidence would have changed the jury’s verdict. Belser also admitted, however, that he had never tried a capital case in Haywood County, had never put on a defense such as the one proposed by Rose’s post-conviction counsel, and knew of no instance where such a defense actually had averted a death sentence. Thus, Belser’s opinion is wholly speculative and is unsupported by the evidence in the record.
Far from undermining confidence in either phase of the State trial, after considering all of the evidence introduced related to Rose’s ineffective assistance of counsel claim, the State habeas court determined that the evidence adduced at the evidentia-ry hearing constituted a “considerably more shocking version of events” that “would virtually have assured conviction of first degree murder” if offered at trial. (J.A. at 266-67.) Additionally, the State habeas court noted that introduction of Rose’s second version of Stewart’s murder, along with Rose’s testimony that he had entered over one hundred other homes and masturbated over people’s beds, would have supported the submission of the aggravating factor in N.C.Gen.Stat. § 15A-
*695
2000(e)(ll), that applies when the murder is part of a course of conduct. Moreover, the State habeas court concluded that, if the jury had been presented with this “repellent” type of sexual disorder evidence, “including as it does rape, torture and murder,” the jury “would have been even more likely to recommend a death sentence.” (J.A. at 275-76). We agree that introducing evidence of Rose’s sexual disorders would have contributed equally, if not more, to the statutory aggravating factors than it would have contributed to any statutory or non-statutory mitigating factors.
13
The alleged mitigation value of introducing Rose’s voyeurism and sexual sadism could not possibly outweigh the detrimental effect that would accompany such evidence because the evidence necessarily introduces components of rape and torture into Stewart’s murder. Thus, we cannot say that a reasonable probability exists that the unpresented evidence would have resulted in a different sentencing decision or that Rose’s counsel’s failure to investigate further into Rose’s sexual disorders constitutes ineffective assistance of counsel.
See Satcher v. Pruett,
V.
Because Rose has failed to make a substantial showing of a denial of a constitu *696 tional right, we deny his request for a certificate of appealability on the claims rejected by the district court. Moreover, because we hold that Rose has failed to establish that he was denied his Sixth Amendment right to effective assistance of counsel, we reverse the portion of the district court’s judgment granting a writ of habeas corpus with respect to Rose’s ineffective assistance of counsel claim.
AFFIRMED IN PART AND REVERSED IN PART
Notes
. No certificate of appealability is necessary with respect to the portion of the district court's judgment from which the State appeals. Fed.R.App.P. 22(b)(3).
. These facts are derived from the statement of facts in the Supreme Court of North Carolina’s published opinion affirming Rose’s conviction on direct appeal.
See State v. Rose,
. Rose also argues that the district court made several factual errors regarding the contents of the record. Without deciding whether the district court erred, we hold that the alleged errors are without substantive effect.
. The North Carolina legislature amended § 15A-1419 in other respects, but the other amendments are not relevant to Rose’s claim.
. North Carolina General Statute § ISA-1419(a)(2) provides that issues raised in a MAR that were previously decided on appeal are barred from further consideration in State habeas review. “In the absence of any proffered reason why relitigation of these claims would have been proper, the superior court is precluded from relitigating issues decided by the Supreme Court of North Carolina.’’
Smith v. Dixon,
. At oral argument, Rose’s counsel also argued that Rose was told that he would not get the death penalty if he confessed. In support of this contention, Rose’s counsel points to Rose's mother's affidavit, in which she states, “I asked Special Agent Frye whether the police would seek the death penalty in the case and [Frye] told Diana and me that the police would not seek the death penalty.” (J.A. at 769.) Nowhere in the affidavit does Rose's mother aver that she relayed this promise to Rose or that the promise was repeated in front of Rose. (J.A. at 769.) Thus, we need not address the coerciveness of this alleged promise.
. Having concluded that Rose has failed to establish the first prong of the
Slack
test, we need not address whether the district court was correct in its procedural default ruling.
See Slack v. McDaniel,
. Before the district court, Rose argued that a claim of economic discrimination is not fundamentally different from a claim of racial discrimination for purposes of determining whether his economic discrimination claim was presented to the State courts. On appeal, Rose concedes that his ''new” economic discrimination claim was never presented to the State courts. (Appellant's Reply Br. at 13) ("Although this claim was never raised in the original state proceedings or in the State Habeas Court....”).
. The one exception to the rule requiring cause and prejudice is where the petitioner is able to demonstrate that the habeas court’s failure to review his federal claim will result in a fundamental miscarriage of justice.
Edwards v. Carpenter,
.At oral argument, counsel expressed no difficulty in having obtained the statistics underlying Rose’s racial discrimination claim. Similar to statistics regarding capital defendants’ race, courts maintain records indicating which capital defendants were represented by court-appointed counsel and are, therefore, indigent.
. While federal habeas courts often use the language of "remand,” as a technical matter, we do not believe that a federal habeas court can "remand” a case to a state habeas court.
See Billiot v. Puckett,
. The State did not object pursuant to Federal Rule of Evidence 606(b) to our consideration of the Chapman affidavit. Thus, to the extent Rule 606(b) is applicable, the State has waived the argument that the affidavit fits within the prohibition of Rule 606(b).
. In evaluating whether to recommend death, the jury was instructed that although the jury must unanimously agree that the government established the existence of an aggravating factor beyond a reasonable doubt, the jury could consider a mitigating factor in its weighing process so long as one juror found that Rose established its existence by a preponderance of the evidence.

The following non-statutory mitigating factors were submitted and were found by one or more member of the jury: (i) Rose was reared until at least his twelfth birthday in the home of his father and mother, the father being a chronic alcoholic who was abusive both physically and mentally to Rose's mother in the presence of Rose; (ii) Rose is the product of a broken home; (iii) Rose received an honorable discharge from the United States Army; (iv) Rose received an honorable discharge from the United States Marine Corps; (v) Rose was a good and obedient prisoner in the Graham County jail for 15 months, and at no time caused any problem with the jailer or other personnel of the Sheriff’s Department or with any other inmates confined there; (vi) Rose was a good and obedient prisoner in Haywood County jail for 12 days; (vii) Rose cooperated with agents of the SBI and members of the Graham County Sheriff’s Departments when he, at their request, agreed to take and did take a polygraph test at a time when he was not in custody and was free to come and go as he pleased; (viii) Rose had been a good and reliable employee of Tucka-seegee Mills for a substantial period of time prior to January 1, 1991; and (ix) Rose had a good character and reputation for truth and veracity in the work community of his place of employment.
The following statutory aggravating factors were presented to the jury and were found unanimously to be applicable beyond a reasonable doubt: (i) Rose has been previously convicted of a felony involving the use or threat of violence to another person; and (ii) the facts surrounding Stewart’s murder were particularly heinous, atrocious, or cruel.
