Maybe this analogy will help you understand what he probably means by being socialized. He is like a wild animal that just happens to have been tamed. I have an aunt who loves having wild animals as pets. Currently it's wolves. She fancies herself a bit of an animal trainer and it's true that the wolf essentially acts just like a dog would. I don't know anything about wolves, but I do know that it is illegal to have a wolf as a pet where she lives, presumably because there is something different about the vis a vis dogs, e.g. they are less domesticated and more dangerous because although they're behavior in that moment is socialized, there's still a greater likelihood that they will act like the wild animal that they are. One of my friends said that being in any sort of relationship with a sociopath is like having a wild, exotic pet. If stories like the lady getting her face chewed off by a chimpanzee or the entertainer who was attacked by his own white lion disturb you or make you think--that person was an idiot to ever trust that animal--maybe being in a relationship with a sociopath is not for you.
