Oh, that this too, too sullied flesh would melt,

Or that the Everlasting had not fixed
His canon 'gainst self-slaughter! O God, God!
How weary, stale, flat, and unprofitable
Seem to me all the uses of this world!
Hath the Everlasting indeed fixed His Canon 'gainst self-slaughter?
The Bible doesn't say anything against suicide. Indeed, the Torah prescribes execution for a wide range of offenses, but nothing for suicide. If you really wanted to end it all, then you could, say, bugger a goat, heal someone on the Sabbath, or go around shouting "Jehovah! Jehovah!" and your friends and neighbors would take care of ending your life for you.
In fact, Jesus himself was on a suicide mission. He set out deliberately to get himself crucified. And, many ancient Christians purposely sought opportunities for martyrdom. I don't know of any modern Christian who isn't too wussy for martyrdom.
Dante, of course, figures on self-slaughterers receiving everlasting torment in Hell.

What say ye? Can one who commits suicide be admitted into Heaven? Or, is it a sin?
