LOL! You just love to poke me to see which way I'll jump, don't you?
All right, then. As you probably expected, I have no problem with anyone killing themselves, regardless of the circumstances. If someone is so down on his life that he can see no other way out, who am I (or you) to tell him he has to deal with it? It's his life, after all.
Granted, most people who have been stopped from killing themselves have changed their minds. But most people who have been stopped weren't really interested in killing themselves anyway. A man who stands on a bridge threatening to jump is more likely to be making a bid for attention or is pleading for help. Give him the help. Talk him down, send him to a hospital and possibly turn him around. But a guy who writes a note, sits down in his chair, puts a gun to his head and actually pulls the trigger? He's not looking for help. He's looking to die. Even if he screws it up and only blows half his brains out, let him die.
I don't see any problem with letting convicted felons kill themselves, either, especially if they've already been condemned to death. Hell, sell them the rope and let them hang themselves in their cells. As long as they have enough money to pay for their burial, why not? Who loses?
