It doesn't mean 'do you want to be a role model'.
In this context, it's being used as a sarcastic profanity.
The way it's read, is extremely questioning and sarcastic. By saying "you're meant to be a role model?", the author is sarcastically remarking that he should NOT in fact be a role model, and that he is very much contrary to that. However, it is implied that people in general look up to him as a role model.
