>MMA fighters can punch a guy to death and it's no big deal even though a girl can just text some hoser to death and go to jail
So, it's obvious that it's perfectly legal for sportsmen to kill eachother so long as they sign the waiver and the intent wasn't to kill. I see no reason why gladiator matches aren't permitted. The intent to kill wouldn't exist there either, and I'd outlaw blows to the head, so I am already more humane than those savage animals who beat eachother to death instead of using the noble path of the sword. Deathblows would also be forbidden, once they go down, that is it, you have to stop. If they died, oh well, that happens and there's nothing that can be done about it.
