And even if people do dislike the victim (which is fair enough), he's still a frail old man. The guy that attacked him is a bottom of the barrel tool.
Seriously, get a grip. He foamed an old man.
He didn't butcher him, steal from him or rape him. He didn't cause injury, he caused embarresment and potentially instilled fear.
If that's the bottom of the barrel I'd hate to see you come up against some real scum.
