Bishop dad obviously had mental issues in the movie and maybe it’s possible that he also suffer from bipolar/ schizophrenia disorder… maybe given false power with a gun, worshipping villainous characters, he to crossed over to the darkside due to not properly being mentally evaluated 
Nino brown even though being surrounded by a tough childhood still had the capability of showing some kind of good and failed at every corner.. ready to eliminate anyone for any lil thing, a complete user and backstabber, pure violence and evil.. killing random innocent 
Remy was an incel that just needed any type of negative influence to go to the darkside..it wasn’t if but when..he’ll look at when the chick got date raped and remy was mad thirsty asking ole boy did he do her good, etc..fucking weirdo
