Oh, give me a break. This wasn't a "fight" where two guys puff themselves up over something and then manfully decide to duke it out.
This was a criminal assault by an unknown assailant on a perfect stranger who he felt "insulted" his friend and whom he decided to "teach a lesson" - and then whom he ambushed with a punch to the head.
The consequences were somewhat predictable for this excessive use of deadly force. And it was deadly.
"Puff themselves up" and "manfully decide"?
LOL, you've never been in a fight, have you? And besides that, your obvious contempt for manliness is dripping down your chin.
It was a street fight.
Street fights are deadly.
Bar fights are deadly.
Grow up.
