UFC fans are still in heated debate about a brutal punch thrown by former Olympic wrestler Dan Henderson at UFC 100 this weekend. Henderson knocked out his “Ultimate Fighter” rival, Briton Michael Bisping, with a vicious right hook, and as Bisping collapsed to the floor, Henderson toppled on top of him, throwing one final blow.

Unlike boxing, UFC doesn’t have a 10 count; many fans (including this one) have argued that Henderson did the right thing by fighting until the bell rings. But the broader moral question must be asked as well: Was the punch necessary to win the fight? It’s unlikely. Which means that if the UFC is barbaric, it’s not because of the fighters, but the rules that govern them.
