It's our life, we do whatever we want with it. If I had sclerosis and that I was nailed to my hospital bed, dieing slowly, unable to breathe by myself, and that I'd want to kill myself, I wouldn't want anyone to stop me. After all, for some people, the courageous, honorful way to dieing is to step up and make the decision. There's a ton of ways to die disgustingly, everyone should have the choice to die with honor, not in one of those disgusting ways. Besides, how would you feel if somebody telled you "no you can't do that" as if you were some sort of little kid, being bossed around.
