Some proof...

...for original sin.

I thought it was interesting that psychological warfare on the parents was correlated to aggressive relationships. One of the great sins is the misuse of our ability to relate to others. When children see their parents using relationships as a method of winning control and power over a situation, they'll imitate this to their own advantage. That shouldn't surprise us.

I wonder how much of this carries over to adulthood. From some experiences I have seen quite a bit. Those rejected by the structure become cynical, at least into early adulthood. Those who gained an advantage through the system cling to it, etc.

At any rate, an interesting bit of research on children.
