If he did lose his daughter he is one weird fucker, he is either a larp or a man who lives by anger and shuts down his emotions. Anger could drive someone that strong.
Yea, I have not figured him out. As a father it might be the only way I could go on without having a breakdown would be to be so pissed off that I wanted to fight the news channels, fight the idiots who lived, fight that fucking sheriff. It may be his way to dealing with it, I do believe people died, so I think that is the answer. Anger, Spite, Hate, Irritation and Nothing To Lose since he already lost his girl.
