Questions like this are appropriate when discussing voluntary euthanasia for terminal medical conditions (which I am in favor of, for the record). They are not at all relevant in cases like this; where Facebook is trying to aid detection and intervention in cases of mental illness when the suicidal person is (literally) not thinking properly.

Nowhere in this discussion is there an implication that suicide is wrong, immoral, or a crime, or that the people should be punished; I don't understand why you're even bringing that up.
