And that's if they even go.
Oh I do believe that there are often deep roots to how someone like this develops. Childhood traumas. Yes. Annihilating, emotionally abusive parents? Yes. Neglect? Hate? Loss?
But having dealt with several personality disordered people both in my personal life and professionally, the ability to actually get disordered people and families help is slim in many cases, if the parents have character disorders.
They never take responsibility and are suspicious and paranoid. They don't have good mental health treatment outcomes.
And much of the disorder in such families would never come close to what is necessary for social services to force services. In fact, much of it isn't close to being on anyone's radar. It's subtle stuff. Like Cindy Anthony alternately stating her daughter was perfect and arrogantly denying that she ever did anything she was accused of as a child, and then being miserably demanding with her daughter and hyper critical. That juxtaposition creates personality disorders.
Or Scott Peterson. How could the subsconsious attitudes and emotions that indicated to him as an infant that any imperfection would cause rejection, how the heck would anyone even realize that was going on, in that seemingly Brady Bunch middle class family?
It's a dream, IMO, that we can fix these families or these people before evil occurs.
But of course that doesn't mean we shouldn't try.
