OPINION
Thе defendant, Tasi F. Pule, appeals from a judgment of conviction for manslaughter in the Superior Court. An indictment charged the defendant with second-degree murder for the stabbing death of James Hathaway. After trial, a Suрerior Court jury found Pule guilty of manslaughter. On appeal the defendant argues that the trial justice erred in admitting into evidence a threatening statement that the defendant made approximately eight weeks priоr to the homicide. We affirm.
This case involves a classic “love triangle” scenario. James “Ronny” Hathaway (Hathaway) and Tasi “Fuji” Pule (Pule) had been friends for two or three years prior to Hathaway’s death. They drаnk together and lived in the same apartment building. In addition, each man eventually became entangled in a romantic liaison with Gloria Moors (Moors).
Moors met Pule in June 1978 and moved in with him in November 1978. In January 1979 Moors left Pule because she and Hathaway had become romantically involved. Shortly thereafter, Pule persuaded Moors to return to his apartment. He told Moors that if she had stayed with Hathaway, he would have killed both of them. Despite this threat, Moors lived with Pule until early March 1979. At that point, she again left Pule and moved into Hathaway’s apartment. Subsequently, she returned to Pule’s apartment, accompanied by Hathaway, to retrieve her clothing.
Initially, Pule and Hathaway began to scuffle outside Hathaway’s apartment, but the fighting ceased when Pule complained about a neck injury. The trio then climbed the stairs to the entrance of Hathaway’s *1097 apartment. Once they entered the apartment, the fight between Pule and Hathaway resumed. Pule grabbed a butcher knife from the kitchen sink, chased Hathaway into the hallway, and stabbed him fatally.
At trial, the prosecutor аttempted to examine Moors about a threat uttered by Pule seven or eight weeks prior to the homicide. Arguing that the threat was irrelevant and prejudicial, defense counsel objected. The trial justice, however, determined that the probative value of the statement outweighed its prejudicial effect. He therefore allowed the testimony. The only issue on appeal is whether this ruling constituted an abuse of disсretion on the part of the trial justice.
It is a well-established principle that the prosecution cannot introduce evidence of an accused’s bad character unless and until the accused offеrs evidence of his or her good character.
McCormick’s Handbook of the Law of Evidence
§ 190 at 447 (2d ed. Cleary 1972);
see Michelson v. United States,
The defendant characterizes his threatening statement to Moors as a prior criminal act. He concedes that this court has articulated a recognized exсeption to the traditional exclusionary rule; namely, evidence of prior criminal acts may be used to prove “guilty knowledge, intent, motive, design, plan, scheme, system, or the like * *
State v. Colangelo,
Clearly, the parties predicate their contentions on the assumption that Pule’s threatening statement concerning Moors and Hathaway was evidence of prior criminal activity. Neither the state nor defendant, however, articulates the crime that Pule committed when he uttered the statement. We are of the opinion that a threat to kill without more does not constitute a criminal offense undеr the laws of this state.

Pule did not assault Moors because he did not accompany his statement with force or violence. General Laws 1956 (1981 Reenactment) § 11-5-3;
see State v. Pope,
R.I.,
Evidence of a prior threat made by a defendant is relevant to the question of whether the defendant “acted with malice or premeditation, or whethеr he had a motive to commit the crime.” 1 Wharton,
Criminal Evidence
§ 201 at 414-15 (13th ed. 1972). Although motive is not an essential element of murder, “[ejvidence of motive is often probative and relevant, and therefore admissible in proper circumstances. * * * [S]uch evidence must not lead the jury to speculate and must not improperly open up collateral matters.”
State
v.
Gazerro,
R.I.,
The defendant admitted stabbing Hathaway but claimed that he had acted in self-defensе.

He argues, therefore, that the only issue for the jury’s consideration was his precise state of mind at the time of the stabbing. This contention assumes that defendant’s assertion of self-defense establishes conclusively thаt he committed the act of stabbing the victim. In any prosecution, however, the state must establish that the defendant committed the act that constitutes the crime. 1 Wharton,
supra
§ 186 at 351. The due-process clause of the Fourteenth Amendment requires that the state prove all facts necessary to establish guilt beyond a reasonable doubt.
In re Winship,
Further, the assertion of self-defense refutes the element of “unlawfulness” necessary for murder in this state.
In re John Doe,
R.I.,
The trial justice specifically ruled that the defendant’s threatening statement was relevant to his motive for committing the crime. Recognizing that the statement was prejudicial to the defendant, the trial justice properly balanced this prejudicial effect against the probative value of the statement before he admitted it into evidence. This court will not consider such evidentiary rulings reversible error unless the trial justice abused his discretion.
State v. Chaplow,
R.I.,
For the reasons stated, the appeal of the defendant is denied and dismissed, the judgment of conviction is affirmed, and the papers in the case may be remanded to the Superior Court.
Notes
. Threats of bodily injury may be criminal in circumstances that are not applicable here. See General Laws 1956 (1981 Reenactment) § 11-13-9 (threats to place bomb or explosive device in public or private building); § 11 — 42— 3, as enacted by P.L. 1982, ch. 373, § 1 (threats to injure person because of his or her race, religion or national origin); cf. § 11-53-2, as enacted by P.L. 1981, ch. 60, § 1 (criminal offense to bum or desecrate cross or other religious symbol with intent to threaten personal injury).
. Even if the statement were a criminal offense, such as extortion, it would have been admissible under the exception enunciated in
State v. Colangelo,
. Pule testified that Hathaway started the fight inside the apartment, grabbed the knife from the sink, and chased him into the hallway. He stated that he threw a table lamp at Hathaway, who dropped to his knees. Pule admits striking Hаthaway with a chair, but claims that he and Hathaway then struggled on the floor for possession of the knife. Pule testified that he grabbed the knife and stabbed Hathaway several times after Hathaway had tried to grab his leg. Gloria Moors rebutted Pule’s claim that Hathaway was the aggressor. Although she did not observe the fight in the hallway, she testified that she heard Hathaway plead, “No, no, I’m your friend.”
