Offended

“I am offended by a blank wall, and if you are not equally offended, I’m even more offended,” Dr. O taught.
A central feature of a personality disorder is an externalized ‘locus of control’.  Developmentally such a person is fixated before the development of self awareness, at a time when their emotional senses are attributed to the environment.  Some theorists say that they have not severed the umbilical cord remaining as an infant emotionally despite outwardly having an adult body and lizard like intellectual development.  
Sociopaths use such individuals as weapons, shields and battering rams for their own personal agendas of greed and self agrandisement. Such sociopaths can claim to be helping these individuals while using them to advance their own power with plausible deniability.
In political jardon these individuals constitute a significant portion of what were called  ‘useful idiots’ or ‘useful fools’.
Like sociopaths they have superego lacunae and lack  the capacity for empathy. Given sociopaths commonly use such individuals for camouflage it’s worthwhile to to think of them as part of the sociopath ‘nest’.
Among emotionally healthy individuals these developmentally delayed individuals would grow and adapt but among sociopaths their disability is sadly tragically capitalized and promoted.
