Suicide is a valid option, and I wouldn't judge anyone for doing it, although there are certain circumstances that I would be more open if I heard about a suicide. Sometimes people who commit suicide do so when they cannot see the light at the end of the tunnel, when in fact there is one.
I can understand someone in chronic severe pain that is untreatable and who has lost pretty much all functioning and cannot be the person they wish to be committing suicide. There are situations where that seems like the most valid option, but only when existence is so unbearable and you have exhausted every option to change that.
I feel that everyone has a right to end their life if they deem it necessary. I don't think most people wish to end their own life at this point, but for those that do, they should have that right. Suicide should not be illegal, but then again, if you do succeed, you're not going to jail, are you? If you fail, you end up in a mental hospital for a 72-hour psych hold with no rights at all until you get out or are deemed a danger to yourself or others and get stuck there for a long time...
