Naw it ain't ever the answer breh...violence begats violence, and when it comes to violence against women as a man you playing a game with the deck stacked against you. It looked/sounded like a room full of women too so yea he was fukked. Unless they coming with weapons to do real damage(gun or knife) his only "defense" should be to protect himself like he did and run up out the situation. The only thing he really did wrong was not disarm ole girl with the belt especially before she could swole his eye with it.
His busted eye would just be more evidence that they should be locked up for a good minute.
At the end of the day if you cheat you get what you get so me i would have just got out safe and let it go. You win some, you lose some...but you live, you live to cheat another day
