Bobby Lewis Shaw, a Missouri death row prisoner, appeals the district court’s dismissal of his second petition for a writ of habeas corpus. We affirm.
*183 I.
While Shaw was incarcerated in Missouri in July 1979, he killed Walter Farrow, a prison corrections officer. The evidence presented at Shaw’s trial shows Shaw calmly and deliberately killed Farrow in the course of carrying out a plan to kill Clint Wyrick, the warden’s uncle and a prison commissary employee, for payment.
Before the murder, inmate Byron Berry overheard Shaw’s discussion with a fellow inmate. The fellow inmate asked Shaw, “When are you going to do that?” Shaw responded, “I’m going — might as well do it, now.” Shaw or his fellow inmate mentioned a ring as payment and the name “Clint.” Shortly after this conversation, Shaw entered the prison’s vegetable preparation room where he worked.
Following normal prison procedure, Officer Farrow had checked out two butcher knives and fifteen paring knives from the prison’s cold storage area. The inmates Farrow supervised used the knives to prepare fresh vegetables. Shaw removed the two butcher knives from an unlocked cabinet where Farrow had placed them and stabbed Farrow in the chest, inflicting a wound seven inches deep. With knives in hand, Shaw ran out of the room and down the hall to the prison commissary where Wyrick worked.
Wyrick was sitting at his desk when Shaw entered the room. Shaw moved quickly around Wyrick’s desk and began stabbing at Wyrick’s chest with both butcher knives. Wyrick fended off many of Shaw’s blows with his right arm, but Shaw was able to stab Wyrick once in the chest and twice in the stomach. After stabbing Wyrick for at least thirty seconds, Shaw ran out of the commissary.
A guard heard of the stabbing and ran outside to seal off the area. As the guard attempted to close a gate, Shaw approached and told the guard to get out of his way. When the guard refused, Shaw pulled the two butcher knives from his waistband and moved towards the guard. The guard retreated and Shaw went through the gate. After the guard shouted to another guard to close the next gate in Shaw’s path, Shaw ran through that gate. Shaw stopped and surrendered, however, when he heard the guard order a tower guard to shoot Shaw if he continued to run. Walter Farrow died from the wound Shaw inflicted.

A jury convicted Shaw of capital murder and recommended the death penalty. The Missouri Supreme Court affirmed Shaw’s conviction and sentence on direct appeal.
State v. Shaw,
After the denial of Shaw’s first habeas petition, Shaw’s second habeas attorney obtained previously unutilized prison records concerning Shaw. Shaw focuses on a prison medical record showing he was hospitalized for psychiatric observation for ten days in February 1978 based on a report that he hallucinated hearing voices one night. The prison records also contain a report by investigating officers stating another inmate asked Shaw to kill Wyrick for a diamond ring, school records documenting Shaw’s low intelligence quotient, and family information. Shaw’s second habeas attorney also obtained an affidavit from Shaw’s mother and sister reporting Shaw’s odd behavior beginning in his childhood. Belying primarily on this information, Shaw filed his second federal habeas petition in 1990, raising four exhausted claims: (1) he received ineffective assistance of trial counsel because counsel failed to investigate and present evidence of Shaw’s diminished mental capacity during the guilt and penalty phases of Shaw’s trial; (2) he received ineffective psychiatric assistance at trial because the psychiatrist was not furnished with the prison records; (3) the jury should have been instructed on Shaw’s diminished

mental capacity during the penalty phase of his trial; and (4) contrary to
Mills v. Maryland,

After a state prisoner’s first federal habeas petition has been decided, federal courts generally cannot consider the merits of claims raised in the prisoner’s later federal habeas petitions. Federal courts must usually dismiss claims raised in later habeas petitions as successive or abusive.
See
28 U.S.C. §§ 2244, 2254 rule 9(b) (1988). Repetitive claims that have been “raised and decided adversely on the merits in an earlier petition” are successive.

The cause requirement focuses on the petitioner’s conduct.

Shaw concedes he raised his ineffective assistance of trial counsel claim in his first petition. Because the first habeas court decided this claim on the merits,
see Howard v. Lewis,
Shaw cannot show cause for not bringing all the evidence supporting his ineffective assistance of counsel claim in his first federal habeas petition.
See Sawyer,

B.
Shaw concedes he raised his second, third, and fourth claims in state court then omitted them from his first habeas petition. Nevertheless, Shaw asserts his first habeas attorney did not know of the supporting facts or law and this lack of knowledge establishes cause. Again, we disagree.
The factual and legal bases for Shaw’s three omitted claims were known or reasonably discoverable by Shaw when he filed his first. federal habeas petition. Shaw’s ineffective assistance of a psychiatrist claim is based on the theory that if Shaw’s court-appointed psychiatrist had been provided with the prison records, the psychiatrist would have discovered and testified about Shaw’s diminished capacity. The case Shaw relies on to support this claim,
Ake v. Oklahoma,
Next, Shaw raised his diminished capacity instruction claim on direct appeal,

As a matter of law, Shaw cannot show cause. We thus reject Shaw’s contention that he is entitled to an evidentiary hearing on cause.

Although Shaw cannot show cause, the district court also has authority to address the merits of Shaw’s constitutional claims if Shaw shows a failure to entertain the claims would be a “miscarriage of justice.”
Sawyer,

Under Missouri law, Shaw was eligible for the death penalty because the jury convicted him of capital murder — deliberate and premeditated killing — and found at least one statutory aggravating circumstance. Mo.Rev.Stat. §§ 565.001, .008.1, .012.5 (1978). Shaw asserts he is innocent of capital murder because the jury would have found he did not possess the necessary ability to deliberate or premeditate if it had considered the, prison records and family history undiscovered due to his trial attorney’s ineffective assistance and an expert opinion based on that information. To support his assertion, Shaw presented the recent affidavit of the court-appointed psychiatrist who testified at Shaw’s trial and the opinion of a psychologist who recently examined Shaw to determine his competence to be executed.
At trial, Shaw’s court-appointed psychiatrist testified that Shaw is borderline mentally retarded and susceptible to suggestion because of his low intelligence, but capable of resisting suggestion and forming the intent necessary to commit capital murder. After recently learning the facts contained in the prison records, family affidavit, and reports of other mental health experts who have examined Shaw since the trial, the psychiatrist now states that the evidence and reports “cast[] significant doubt on the reliability and accuracy of [his earlier] opinion that Mr. Shaw did not suffer from a mental disease or defect [when he committed the murder].” The psychiatrist states the additional facts “would have affected [his] diagnosis” of Shaw over ten years ago and the psychiatrist “now believe[s] [Shaw] was suffering from the onset of early dementia, and possibly early chronic schizophrenia.” The psychiatrist, however, states he needs more information to reach an accurate opinion about Shaw’s mental condition at the time of the murder. The psychiatrist does not offer an opinion about Shaw’s ability to deliberate and premeditate at the time of the murder.
The psychologist who recently examined Shaw also reviewed some of Shaw’s prison records and school reports, administered psychological tests, and reviewed reports of psychologists and psychiatrists who examined Shaw years after the murder. Based on his evaluation, the psychologist believes Shaw suffered from brain damage when he committed the murder and command hallucinations probably played a role in Shaw’s commission of the murder. The psychologist, however, does not state these problems nullified Shaw’s ability to deliberate and premeditate. The psychologist also acknowledges his opinion, rendered more than eleven years after the murder, is speculative.
Given the prosecution’s evidence of Shaw’s actions on the day of the murder, we believe the jury could still reasonably infer Shaw acted deliberately and with premeditation even if it had considered the prison records, family affidavit, and recent opinions of the two mental experts. The evidence presented at trial showed Shaw planned to kill Wyrick and calmly killed Farrow in the course of obtaining weapons to carry out his plan. No facts surrounding the murder suggest Shaw heard voices, acted under the substantial domination of another person, acted irrationally, or otherwise lacked control of his faculties.
Shaw has simply presented no new evidence connecting his supposed mental deficiencies to the murder. Contrary to Shaw’s assertion, the specified prison records, family affidavit, and expert opinions do not show Shaw suffered from a mental disease, hallucinated hearing voices, or was subject to domination at the time of the killing. The records contain no statements by inmates or prison personnel stating Shaw was acting irrationally or bizarrely
*187
near the date of the murder. The psychologist’s opinion that Shaw hallucinated at the time of the murder is purely speculative. Further, the psychiatrist’s equivocal affidavit stating he would have testified differently about Shaw’s mental capacity if he had known the information contained in the records falls far short of showing . Shaw lacked the ability to deliberate or premeditate at the time of the murder.
See Romero v. Collins,
Alternatively, Shaw contends he is innocent of the death penalty because the jury probably would have recommended life imprisonment instead of death if the prison records, family history, and an expert opinion based on them had been admitted during the penalty phase of his trial. Shaw contends that if this evidence had been admitted, he would have received statutory mitigating instructions. See Mo.Rev. Stat. § 565.012.3(2), (5), (6) (1978). Shaw also contends that he would have been sentenced to life rather than death if the trial court had instructed the jury that it could consider a mitigating circumstance even if the jurors did not unanimously agree the circumstance existed.
Shaw’s contentions do not affect his eligibility for the death penalty because they relate to mitigating rather than aggravating factors.
Sawyer,
— U.S. at-,
In sum, Shaw has not satisfied his high burden to show “clear and convincing evidence that but for a constitutional error, no reasonable juror would have found [him] eligible for the death penalty under [Missouri] law.”

The district court dismissed Shaw’s incompetence claim as successive because Shaw claimed he was incompetent to be executed in his first federal habeas petition and the earlier habeas court denied this claim on the merits.

Having considered all of Shaw’s arguments, we affirm the district court’s dismissal of Shaw’s second federal habeas petition.
