When the guy throws the cigarette back at him, Chopper says "You don't much like me, do you, Keith." This all happens in the first nine minutes of the film. Then, as the guy lies on the floor in a huge pool of blood, Chopper asks him if he's all right, tells him it's going to be fine, and offers him a cigarette. So, without any provocation whatever, he comes up to the guy during exercise and stabs him multiple times in the face. Establishing Character Moment: Chopper decides that for him to be the most powerful guy in his prison division, another prisoner has to be got out of the way.When even that doesn't work, and Jimmy finally backs away with Oh, Crap! written all over his face and suggests that it might be a good idea for Chopper to lie down, Chopper calmly replies "What for?" Then, when he does figure out what's got into Jimmy, he tries to give him a forgiving hug. Then he doesn't understand why Jimmy's done it. At first, Chopper doesn't even notice that it's happened.
