You did.
Some can't.
Clearly. The question for discussion is this: should we, because some can't, force everyone into the government-run psychiatric ward, in the name of their own best interests?
That is the necessary end result of what's being proposed here: that because there are some who end up offing themselves rather than helping themselves, we must put everyone under suspicion of being mentally ill, and must examine them closely because we cannot know, ahead of time, who will, and who will not, turn out to be one of those who "can't help themselves."
Life is tragic. Government simply compounds the tragedy, it rarely, if ever ameliorates it.
