> When that does not happen, they continue these behaviours into adulthood with the expected results.

I am not sure this is true. People brought up the same way can be morally very different. People can be taught right and wrong and do evil. They can lack that education and be good.

I remember reading a long account by the father of a psychopath. If I recall correctly, the kid had at least one other sibling who turned out normal, there was no abuse, quality education, lots of love and affirmation. And the kid still turned out violently antisocial, including against his own parents.

At the end of it he said he wished his child had never been born, despite hating himself for feeling that way. It chilled me to the bone.
