From what I've seen of UFC, nothing would surprise me. I genuinely believe that if the ref didn't step in, the winner would carry on and beat their opponent to death. I can't understand why some winners are not DQ'd, because they carry on punching their opponent when the ref has called a halt to the fight. It should be banned in my opinion, along with boxing.
There are plenty of hippocrites around. There seems to be a lot of concern about head injuries, but none at all as far as MMA and boxing are concerned. They should be banned.
