I can imagine John saying something like, "Roy's got an army of fuckin' killers, psychos, drug addicts hangin all round him, I'm gonna fuck with that, and what, end up in the trunk of a car somewhere? Tell Paul to let someone else take care of it, I ain't doin that shit, end up in a fuckin' cement barrel in the East River or chopped up into a dozen pieces. That fuckin' Roy and his guys, they're a gang of animals, I gotta, I gotta stick my neck out to take care of Paul's loose canon crew?"
