Watching UFC, what do you think the audience is there for? What do they shout for? They get entertainment from the violence and blood.

Boxing is even more despicable, since its even more poorly regulated.

Physically better your opponent? Try wrestling.

The aim of MMA is NOT to injure your opponent into submission. Most fighters will want to avoid injuring their opponent when they attempt to win, as they are only human, and feel guilt if their opponent suffers a bad injury.

Lukily in MMA, bad injuries (beyond cuts and bruises) are relativly rare.

Secondly, how is it any different from boxing, tae-kwon-do and judo, where your aim is to physically better your opponent?

MMA is just a mixture of those sports, nothing else.

Unlike any other sport, there isn’t any other goal but to badly injure your opponent into submission. It isn’t sport; it’s glamourized barbarism.
