So, basically what you're saying, nitsuJ, is it's his choice. Free will, right? Please, correct me if I'm misunderstanding you. Yes, there is free will. And, if through his suicide he doesn't impinge on anyone else, I kind of agree with that.

Free will, though, is not an excuse to whatever the hell you want. I'll have to pinch another quote from Terry Pratchett for this (somewhat paraphrased):

"There is always a choice."
"You mean I could choose certain death?"
"A choice nevertheless, or perhaps an alternative. You see I believe in freedom. Not many people do, although they will of course protest otherwise. And no practical definition of freedom would be complete without the freedom to take the consequences. Indeed, it is the freedom upon which all the other are based."
Basically, that's free will for me. Yes, you can do whatever you want, but you're going to have to face the consequences if you really believe it's an excuse to do whatever you want.

I realise that was a bit of a tangent. I just wanted to get that out.
