Suicide

A wounded Tusken prepares to commit suicide

Suicide was the deliberate termination of one's life by one's own hand. Sentient beings committed suicide for a number of reasons. It could be brought about by the mental status of a person or by extraneous circumstances, such as cultural demands or military directives.

Suicide teeth or poisonous pills were used by some military personnel to commit suicide and prevent capture by the enemy.
