my only concern, if suicide is allowed, is what people will start coming up with. for example, "bob" kills another "john's" wife. bob is convicted and goes to jail for life.

now, suppose bob decides to kill himself. john is going to be pissed! "he took my wife" says john, "it should be I that kill him".

even if the state does not allow john to kill bob, it is still going to cause unrest. "if a man is allowed to kill himself," the people will say, "why not let him be killed by a man that deserves the justice? if bob is allowed to die anyway, does it matter whose hand delivers the blow?"
