Being a role model isn't a choice the person being looked up to makes. some people don't care if people look up to them or not, so they may do and say detestable things (conor, Jones) Some people don't want to be portrayed in a negative light by the general public and would rather spread something positive if they could help it (GSP, Wonderboy).
Joe B is a role model. Whether he likes it or not, but he doesn't have to acknowledge that he is if doesn't want to. He sounds like he does what he wants because HE wants to. not so that people look up to him.
