Way back in high school a buddy of mine got into a fight at a football game with a player from the opposite team. First thing he did was take off his helmet - the other guy kept his on.
Big mistake.
Reviweing the game films the next morning the coach played the fight over several times.
His advice - never start fist fight with a guy wearing a helmet, especially if you are not wearing one. I've followed that lesson for quite a few years.
There is nothing good that will come of it.
