I didn't accuse you of confronting him, I'm just warning you not to confront anyone. Criticizing someone for being vocal about unpleasant events in their past and not healing fast enough doesn't help them heal, it just makes things worse (and makes it harder to heal by pushing the person into repression and denial). Frankly I think he seems to be doing just fine.
Once you do that, I'll give you my opinion. I'm as entitled to do that as anyone.
