The Neo Nazi Idiot

Did anyone catch the episode with the neo nazi who loved violence? He killed a bum just to kill someone. I don't really think he believed in the "Nazi cause," as much as he wanted to be a part of a violent organization, and he was full of hate. I sincerely don't believe he even liked being part of the organization. I never understood what made him snap and put a gas mask on and attempt to murder his neighbor, and kill her son's friend. When they interviewed him, he acted like he had changed his ways, but when he talked about the violence, I sensed no remorse for anything. Also, his tattoos were really bad. Someone should have told him that!
