Suicide

Suicide is commonly defined as intentionally killing oneself. However, if defined thus, there are some odd consequences of such a definition: One can both commit suicide and be murdered or killed by someone else. Socrates both intentionally killed himself and was killed (arguably murdered) by his city-state for the crime of subverting the youth. However, if we add a non coercion criterion in there, we might avoid this intuitively odd entailment.
