Your boy attacked first.
Any single punch can be lethal and any attack always warrants self defense.
In the world of grown up adults, self defense is the only violence that is acceptable. Both a gun and a punch can be intended lethally, or not.
Your boy attacked someone for no cause that you listed, and he paid for that mistake.
You guys all need some adult role models, maybe male, and someone to explain the basics of right and wrong.
Bidness, you not only lack that knowledge and those skills, you will never learn the lesson here.
It is sad that you don't want to break free from chains and because of that you are destined to lose homies and even your own life due to avaoidable, senseless, violence.
Learn what he did wrong and learn from that mistake or you will repeat it yourself.
This time, however, there will be no sad homie to post about it on SBR.
Time for some serious self reflection, Bidness.
