Similar to other deaths during a sporting event, as long as the actor did not violate the rules and intend to inflect harm there is no crime.

There have been deaths from football, hockey, and other sports.

I can only remember one case where a hockey player was charged in a death, because he illegally poked the other player with the end of his stick.

It is murder. A fight to the death contract is not even remotely legal.

There was no malice or bad intention to kill a person. It's just a sport, but accidents do happen. Once you become a boxer, you know that you can get injured or killed anytime.

blah blah blah blah blah

Why is it not murder if a boxer is killed by a punch.. but it's not legally binding to sign a "fight to the death" contract. And the winner would still be considered a murder regardless of both parties signing..

So does this mean that as long as the two "fight to the death" competitors wore gloves and faught in a ring it would be 100% legal.?
