Why Are People So Anti Suicide?

[BladeCNH]

I was reading some threads in this section, and someone said something along the lines of "It's your life, if you want to, no one will stop you" When talking about suicide.

Of course, the guy got called a heartless idiot, so, I was just wondering, why is suicide always seen so badly? There are two kinds of people, those who want attention, who will slit their wrists, but not want to die, and those who will just do it, no warning, the first time.

Of course, the people who slit, should be helped out of whatever is going on and causing them to hurt themselves, but for those who really want to die, why should we tell them they can't?

IMHO, if I wanted to die, I would just throw myself in front of a train, you would be dead in a second with no pain, your head simply explodes, however many people would try something stupid and painful to try and kill themselves, such as silting their wrists, or over dosing. Surly if someone really wants to die, and has made an informed adult decision about it, we should help them do it in the safest, and least painful way, that will cause as few problems for those around them as possible.

If you want to kill yourself go ahead, but Im not doing that.
