Again, this sort of thing is way out of my area of knowledge. But there's the whole.. nature vs nurture thing. It's the way you're raised. If the kid is loved and knows right from wrong, that's what's important.
I mean, I don't know how things are here, but that's how it usually works. Or you get the people like us from my world who rebelled against what our families wanted for whatever reason to do what we love, despite expectations or lack there of, to make our own way without the restraints people expect. So if the kid is 'supposed' to be evil? If they decide to say fuck that shit and rebel against it? That's also possible.
