I think I can speak from experience that children can grow up in pretty fucked-up ways if they're not cared and loved for properly. Because of our parents' divorce and dating history that resulted in a complicated living situation, my sister and I don't want to get married (with other people, of course) and have kids, not sure of my brother, and he was the middle/problem child out of the three of us (the 'Kouto' in our family, but instead of being pitiful and meek, he got into trouble pretty often). At any rate, it's pretty certain that our bloodline will end in our generation.
