I think everyone has the potential to be a pedo. Any fetishes can be cultivated. Getting turned on by breasts is such an example. It's just become so widespread that it's no longer considered out of the ordinary, but do you really think sexual attraction to breasts is instinctive? A lot of people who are full blown pedophiles started out with normal sexual interests, but then explored the field on a whim or out of curiousity, and accidentally let it get out of hand.
