Just to clarify my earlier assertions: I do not think it's good or healthy for a person to use self-mutilation as a coping mechanism for depression. Other than the obvious possible results of real harm (even if it's a staff infection from a small cut) it just doesn't seem like it's in any way healthy. It's just a gut feeling.
What I don't have a problem with is masochism used to derive pleasure rather than to alleviate emotional pain. I'm talking about the guys who go to dominatrixes to get whipped and have hot wax poured on them. If that's what they get off on, more power to 'em. I don't see any harm in that.
As far as people wanting to amputate themselves, there something wrong there . . . but whether or not someone should be able to do it is a more complicated matter--probably moreso than any of us are intelligent enough to understand.
What about this guy:

Should that be allowed?
