I don't think there's any ethical "dilemma" here at all, and it's certainly not any kind of sin in my book.

I don't go around starting fights. That means, if I'm in a fight, it's because some other jackass has started it.

Once I'm fighting, I will do anything, everything, absolutely everything, to put him on the ground and make sure he can't get up. I don't care how big or small he is. I'm either going to win the fight or lose it, but if I lose it's not going to be because I didn't give it my all, or didn't take a clear shot at his balls that would have put him on the ground because it's not "fair".

If I have to rip earrings / piercings out, claw at / poke his eyes, pull his hair, bite him, or even if I have to bite him in the nuts, I will.

There's no such thing as a fair fight, dirty fighting, or any of that crap. There is only the winner and the loser. It's better to be the winner.
