Do you think this kid is a borderline pedophile?

My cousin is 19 and is only interested in dating 12 and 13 year old little girls. We keep warning him that he's gonna get himself in trouble and probably end up in jail but he won't listen. When we tell him he needs to find someone his own age, he says he doesn't like girls his age. It's not like these relationships are strictly for companionship, everyone is aware that they're sexual relationships and that he's sleeping with these girls. He refuses to take anyone's advice and keeps going after these little girls. Do you think the kid's just misunderstood or do you think he's probably a pedophile? Everyone in the family finds his behavior really inappropriate and thinks he's a pedophile but my aunt says he's just an idiot and nothing more. What do you guys think?
