Hello. Well, I think it is to do with how children are brought up and if their home background has something to do with how they turn out. So, if you think that it is all to do with a child's nature, then no matter what kind of home-life or education is provided, the child will grow up to become what he was meant to become. On the other hand, if you look in terms of nurture, then the care, the upbringing a child has will affect his or her destiny and life choices.
I think though that it is a case of both being correct.
