I agree. Dean's never been given the chance to consider other options, never entertained anything else. Just because he's good at everything doesnt' mean he's destined to do this one thing. Though, I really don't have a problem with the stipulation that he's born to hunt. I mean, I know a lot of people who are good at just about everything, and it's really not a lot of fun to be that way. It's so much harder to find the ONE thing that's your true passion. I don't think this episode established that this was Dean's ONE thing, but I think it would've taken more than one episode to do that, and they just flat-out cheated.
