My take on BPD is that it is a fake label, made up by "reformed" BPD's in the field. It's the lowest on the totem pole for the cluster B's, which succeed as follows; BPD, HPD, and AsPD...As for NPD, it does not belong here (although the new DSM is removing this and referring to Cluster B as the "Dramatic Cluster", which in a way it is. But in my opinion, it greatly differs from any type of sociopathy (AsPD). If you think about it, narcissists aim to make you dependent on them through deception and manipulation, while sociopaths seek outright control over someone. Also, Narcissists can empathize but only for themselves, while sociopaths have no ability to empathize at all. They pretty much just follow instinct and thus are “selfish” in their pursuits....A “survival of the fittest” mechanism.
But I feel that with the exception of codeps, all narcissists are horrid people, whereas all sociopaths are not.
Now here is the twist in my theory; AsPD can be comorbid with narcissism…and these are the most despicable/evil humans to walk the Earth (think Hitler…better yet, the embodiment of The Devil himself). Their aim is to have absolute control by any means without regard to any boundaries...societal or personal. But thisnarcissistic comorbidity can run hand-in-hand with any of the remaining cluster B’s. I.e. Add Narcissism to BPD and that would give you Histrionic.
I am implying is that there are degrees of sociopathy, which can be exhibited in virtually anyone and narcissism is not a high form of it but separate…and when comingled, narcissism multiples the nastiness of sociopaths by a significant degree. BPD's have little narcissism, HPD's much more. AsPD's are higher on the sociopathic spectrum but this does not mean they have a degree of narcissism...add Narcissism to
AsPD and you have Hitler/ Satan.
