To the OP. Ultimately people do what they want in moods and crises. It's the hope of a better future that dissuades suicide unless the intial impulse is strong, sudden and the means is too easily at hand. In assisted suicide debate, it all depends on case by case basis and probability of reasonable life, likelihood of cure or manageability. When unbearable pain and gross loss of individuality and dignity is there, then someone has to make a decision either way for the sake of the affected person, which trumps all other things. That is my personal views on that.
