That group of guys with the beer muscles thought they had almost killed somebody they were trying to persecute, since beer muscles can throw somebody's sense of reality off. They didn't even really black the guy's eyes, he just had a bloody nose and that was about it. You would think as many times as they hit the guy, they would have been able to really fuck him up badly, then he really would have been lucky to be alive.
