Murder-suicide

A murder-suicide is an act in which an individual kills one or more other persons immediately before, or at the same time as, killing himself.

The combination of murder and suicide can take various forms, including:
 * Suicide to facilitate murder, as in suicide bombing
 * Suicide after murder to escape punishment
 * Having a combined objective of suicide and murder
 * Suicide after murder as a form of self-punishment due to guilt
 * Considering one's suicide as the main act, but murdering one's children first, to avoid them becoming orphans, to be together in an expected afterlife, in the context of severe depression where the person feels he is sparing his loved ones from a horrible life, or simply just to experience the act
 * Joint suicide in the form of killing the other with consent, and then killing oneself
 * Some cases of cult suicide may also involve murder
 * Suicide in a group setting that necessarily causes the death of others, such as an airplane or train bombing.
