It would seem he's under a tremendous amount of stress, for sure. It always seemed to me (very unscientific) that the whole mess arose because he wanted to feel more powerful and in control than he actually was. Where he ended up was a place where he was in NO way in control of his life....so waving a gun -- if indeed he did -- wouldn't be at all surprising to me.
There are probably millions of George Zimmermans in the world, trying to exercise control over their lives with the aid of firearms. Hard to say if he deserves any more help than any of them do.
