It is widely understood that psychopaths can’t attach to, or bond with, others.
“The ‘house of psychopath’ is constructed on a foundation of no attachment, underarousal, and minimal anxiety. These appear to be necessary, related, but insufficient characteristics that provide certain biological predispositions for the development of the psychopathic character. Attachment is a biologically-based, species-specific behavioral system which serves the survival of the infant by maintaining the closeness of the caretaker. It is deeply rooted in mammals, but absent in reptiles.” ~ A Psychoanalytic View of the Psychopath, J. Reid Meloy, Ph.D., San Diego Psychoanalytic Society and Institute
Now I understand where the book “Snakes in Suits: When Psychopaths Go To Work” really got its title.
