Suicide is the act of deliberately killing oneself. People commit suicide out of despair, to escape suffering, to avoid shame or humiliation or sometimes as a political statement.
According to Buddhist ethics, suicide is a negative action similar to murder. Whereas murder is destructive emotions and intentions directed towards another, suicide is the same or similar negative states directed towards oneself. It is an offence entailing expulsion from the Sangha for a monk or nun to encourage someone to commit suicide or to assist them in doing so. Suicide is unknown in Bhutan, while Sri Lanka has had for many years either the highest or second highest suicide rate in the world.
