... Just... WHY would he rip his own teeth out?
Seriously... that kind of sick idealism is beyond fucked up.
The answer to this situation is quite straightforward: Two guys with different ideals fight, one dies, the other wins. Who would mutilate their own face for the sake of claiming some meaningless sense of righteousness? The horse aggroed him, so he is fully within his rights to vector the fucker through the window... IF he can.
I just hope the teeth can be put back in.... otherwise he'll be drinking soup for the rest of his miserable life.
