Suicidal behaviour continues to be considered as criminal behaviour in several parts of the world, even though most countries have de-criminalized it. This chapter will explore the origins of this belief and the process by which the transition of suicide from sin to crime took place in a global perspective across different cultures. Therefore, the impact of such criminalization and de-criminalization of suicidal behaviour will also be explored. Finally, this chapter will examine the connotations of definitions of suicidal behaviour and suggest progressive ways of considering suicidal behaviour, neither as sin nor as crime but as psychological distress. Case histories will be used as illustrations.
