Not to derail this thread, but I'm with el Barto. I know two people personally who committed suicide, and one was, if not a close friend, then certainly a good friend. He was a cop in a big City (Philly), and he put his life on the line too many times to count. He was many things - troubled is certainly one - but "coward" is not. Neither one would have been in your top 15 list of "People you think would commit suicide". This was his decision, and while it has benefits for us as a society, I think that's as far as we can go with that.
