Well when he hit back I was like, yeah, she had it coming...
But when he started attacking the other woman out of fear and knocked the girl when she was down it was enough.
Considering their culture is a bit backward and that violence crimes are pretty frequent, I don't think it's that "shocking" there. But he did go too far even though she provoked him a lot.
at this being under Live Performances 
but when she fell to the floor after 4 hits, that was enough.
