Well, I'm trying to think here.
I won't take that shot out of professional courtesy.
It's safe to say Serial Killers and what not are all worse than rex. But it's safe to say somebody has murdered someone who had it coming. I just can't think of an example.
There was this grandma who shot the guy who raped her grandaughter in the balls. That's cool. I just can't remember if he died...if so than rex is worse than her.
Well, if it's justified then it's not murder, is it? It's manslaughter, or something.
