That's definitely the way I see it, the whole setup is just a way to show what RR can be like. I think it's actually deeper than him just being a douche, RR is a pretty traumatized individual who constantly acts out in dangerous ways. He is a seriously unstable and hurt individual and out of all of the Guardians his tale is the worst. I always felt sorry for RR. Soft spot for anthropomorphized weapon toting raccoons.
