I think you're putting too much emphasis on social experience (whatever that means). I think that what they read is a far more influential factor in making (at least some) of them decent (or not) toward one another. I was quite the hell-raiser in my youth, and I would have remained so into my twenties had I not found reasons to do otherwise. These reasons could not have come from my peers, because even if they knew them (which was not the case), they were not developed well enough to articulate them.
