A sucker punch to the head
head stomping people once they drop to the ground.
all grounds for attempted murder
I won't even feel sorry for anyone caught up doing this. Especially dudes that stomp on the head during a fight.
Punching someone unbeknownst to them is some coward shyt. Like walking up behind some random person in Walgreens and punching them in the side of the face or head is cowardly, no justification.
A lot of these acts aren't random. If you say some slick shyt, then turn your back, it's not over. If you talk that talk on the internet or on the phone you don't get to complain when you get caught in public or at work or wherever and it's on sight. If that's how you feel then be the bigger man and keep your mouth shut and don't do stuff that'll get you put on sight notice.
Fights are fights until they are broken up by others or someone is knocked out or quits/runs away. If you are engaged in mutual combat you have to do what you have to do to survive. If you can knock them out standing up, take your shot, if they get knocked down but not knocked out and are still fighting, havent quit and you are at the advantage of standing over them kick those ribs, stomach, head, face, stomp on a knee, ankle, femur, hand, do what you gotta do.
Fighting ain't supposed to be pretty, it's not the movies. There's no honorable fight. These rare fights you see where someone gets combo'd or two pieced and they are like "

enough, enough!" And they dap it up, hug and apologize ain't some man shyt or some respect shyt, it's a lack of social skills and problem solving they could've gotten to that point without engaging in physical contact. As far as other fights where people get knocked out, stomped out that wasnt on some coward, blindsiding shyt it's still a lack of communication, social skills, problem solving but that's there only way.
Y'all want to fight and take the moral high ground. It's survival, life or death. If a person starts punching you and has a rope they intend to tie around your neck and hang you from a tree, you not gonna stomp their head if that what separates you from getting lynched? Some dude tries dragging your kid into their car, you're fighting them they aren't actively fighting back but scrambling to get away, you gonna hold them down?
If you find yourself engaged in battle, you gotta do what you gotta do, bite, pinch, gouge eyes, pull hair, kick, punch, choke. It's not a boxing match, it's not mma.
That's not saying every fight has to end in a knockout, grievous injury or death. If your in a position where you can retreat whether from a standpoint of an advantage (winning the fight) or losing do what you gotta do to say "it's over, I'm done" even if you gotta run away.
Most people aren't crazy, they aren't gonna stomp your head. If yiure getting your head stomped you probably did some shyt. It's like crimes of passion, someone's not going to just stab you 36 times cause they crazy, or smash your face 40 times with a hammer, that shyt is personal.
