Bishop was always a psycho, his peoples didn't realize until he killed Raheem.
Bishop got excited when Blizzard stuck up the bar and manipulated Raheem to get the gun after:
Q was the only one who saw it when he called him crazy the first time, it was too late:
He was acting like he was down with the crew until he got what he really wanted:
"We crew, always will be... ain't no man above the crew, you know that shyt."
A couple lines of dialogue after being called crazy again, "I don't give a fukk about you, I don't about Steel, and I don't give a fukk about Raheem, either. I don't give a fukk about myself. Look: I ain't shyt, I ain't never gone be shyt."
Dude sacrificed the crew because he was too weak to do his own dirt and knew it.
Deep down he hated the crew as much as he hated Radames for similar reasons.
The horror twist was at the start of the movie, @1:46
Peep the gun necklace.
Bishop was always a psycho. Some of y'all woulda been food fukkin' with him.
