Speaking as a person who has had friends/loved ones commit this atrocity, and speaking as a person who has had a pistol in his mouth more than once, I would like to put in my two cents worth and hope no one kills themselves over it.

BULLSHIT!
Suicide is the single most selfish act you can commit. And you can't undo it.
I could understand it if there is a pain/suffering issue, maybe.
Understand it, yes. Forgive it? Haven't been able to manage that one yet.
