"Malice Aforethought"
Under many state laws, perpetrators of first degree murder must have acted with malice or "malice aforethought." Malice generally includes an evil disposition or purpose and an indifference to human life. States treat the concept of "malice" differently. Under some laws, malice aforethought essentially means the same thing as acting with a premeditated intent to kill or extreme indifference to human life. Other states require a showing of malice distinct from the willfulness, deliberation and premeditation generally required for first degree murder.

Many states also categorize certain methods of killing as murder in the first degree. These include intentional poisonings, murders resulting from imprisonment or torture and murders in which the killer "laid in wait" for or ambushed the victim.
