I agree with deliveryman. You don’t understand what protagonist means.
Protagonist doesn’t mean “the good guy”, it’s just the main character (or otherwise the character that the story is about.)
Vincent is the protagonist in the first story, Butch in the second, and Jules in the third.
EDIT: Oh, deliveryman already posted “THE ANSWER”. This is what you get for not noticing that there’s more than one page of replys.
