Damian did nothing wrong
The entire excuse in this movie is that they were kids. Yeah...and??
I mean, Adonis got off 100% scott free for assaulting a man, while Damian took the fall and spent 18 years rotting in prison, lol. I know Damian had a gun and whatnot, but still...
It's like if you caused a car accident that injured someone, but you sped away before the police showed up and before anyone could get your plate number. But someone else who was there on the scene, took the fall and went to prison.
