I'd strongly suspect emotional problems as well. But... even if he was evaluated and his therapists told him don't go under the knife, he can still do whatever he wants. No different than a doctor telling a pt to quit smoking, it is making them sicker.... but they continue anyway.

He did seem fine with himself last night, so I wouldn't go any further than that really. He may very well turn out to have a grounding influence on the rest of the house... hard to tell anything really this early on...
