Absolutely, a crowd adds to the anxiety, the tension, the adrenaline rush, the desperation of the contenders and the depth of the violence within the fight. It sets a higher dominance and humiliation level
as being at stake. It is the very best, the only natural way, to fight, in my opinion. If one fought in olden times, you would have to fight in front of the tribe or the village. If you are going to put yourself on
the line, then one should do it all the way.
