Malice

Malice is a state of mind that compels a person to deliberately cause unjustifiable injury to another person. At Common Law, murder was the unlawful killing of one human being by another with malice aforethought, or a predetermination to kill without legal justification or excuse. Most jurisdictions have omitted malice from statutes, in favor of less-nebulous terms to describe intent, such as purpose and knowing.
Massachusetts, for example, has retained malice as an element in criminal prosecutions. Under the General Laws of the Commonwealth of Massachusetts, Chapter 265, Section 1, malice is an essential element of first- and second-degree murder. According to the Supreme Judicial Court of Massachusetts malice is a mental state that "includes any unexcused intent to kill, to do grievous bodily harm, or to do an act creating a plain and strong likelihood that death or grievous harm will follow" (Commonwealth v. Huot, 403 N.E.2d 411 [1980]).
