The idea that because something turned violent there is never any forgiveness or just dismissal, just because you are 'street' is not true.
That's just 50's persona. Plus, he's clearly hooked to the drama and likes on instagram which is embarrassing, but that's just life now. Gotti and Doplh kinda did the same thing. I could tell my own experiences, but sometimes it's just over, and you realize the person isn't worth hating, or carrying a grudge. The same way you can fight someone and laugh about it years later. It's not that different. People's egos get caught up in the game.
There's like drug trafficking organizations that have committed murders up and down both sides, and they just decide: no more. Major gang leaders who lose family members just say we are going to stop this, and shake hands and move on. Doesn't mean we are boys, but sometimes you become friends too. I ran into a dude I've known since like 5th grade, we got into an issue like 20 years ago, we fought, but we kept it kinda cool after, and then years later when I saw him we hugged and shook hands like men, and we both apologized for what went down, just like that.
