I answered yes to the question, but to be honest, that question makes no sense whatsoever. If the question were "Should assisted suicide be legal?" then I would understand the reasons to talk about it. But asking if suicide should be legal is pointless. What are you going to do to those who commit suicide? Put their dead body in jail? Seriously?!?

It takes a few seconds to kill oneself. While such act is not always done rationally, a big trauma in someone's life can lead to a quick decision out of a moment of sorrow and despair. If you generalize it saying that by definition suicide is an act of mental illness, then you are a very close-minded person. Life is not all black and white.
