Premeditated murder is the crime of wrongfully causing the death of another human being (also known as murder) after rationally considering the timing or method of doing so, in order to either increase the likelihood of success, or to evade detection or apprehension. State laws in the United States vary as to definitions of "premeditation." In some states, premeditation may be construed as taking place mere seconds before the murder. Premeditated murder is usually defined as one of the most serious forms of homicide, and is punished more severely than manslaughter or other types of murder - often with the death penalty or a life sentence without the possibility of parole.

La préméditation est l'intention mûrie et délibérée de commettre une action, surtout mauvaise.
