I think a useful tool in analyzing the distinctions between types of personality disorder is to look at them as they are presented through art. What characters in fiction do you think show the symptoms of HPD?
For me, some that come to mind are:
Abigail Williams in The Crucible. I don't mean the real Abigail Williams, because she was very young at the time of the trials (I do think the witch trials were a result of a huge number of HPD sufferers, however). I mean the one composed by Arthur Miller, who is actually a composite of many of the actual figures in history, namely Mercy Lewis, whose role in the trials is downsized for the play. Abby is 16 in the play and is in love or desire with a married man, and is literally willing to do anything to get closer to him. When he gets hanged for being a witch, Abigail is relatively without qualm, because he had told her he would never want her again. She actually skips town when she is put under scrutiny for what she's done, demonstrating the avoidance of consequence in HPD. Abigail also demonstrates an ability to manipulate those around her (especially those prone to hysterical symptoms). And though able to pretend she is under the influence of illusion, she is also able to calm herself down and regroup for better efficacy.
Mary Warren and Mercy Lewis, also in The Crucible. These two are more demonstrative of hysterical personality, as they are easily influenced a lot more than they are able to willfully deceive. All of the girls have a huge desire to get married, which could have been a huge catalyst for their psychopathy. In fact, in reality, Mary Warren's real life counterpart stopped having symptoms of affliction as soon as she got married. In the play, her symptoms are controllable by the suggestion of John Proctor, the man for whom she keeps house. She is unable to fend off the suggestion of the other girls when on stand in court, however, which sends her into hysterical psychosis. Mercy, on the other hand, is less instrumental in the play but also takes part in the psychotic symptoms. Before the play begins, she is spotted in the woods running naked as the other girls do a ritual. She runs away with Abby before the final act of the play.
I think James Cook of Skins UK could be HPD, but that could be a very heedless analysis. He doesn't seem to have sexual problems besides being uninhibited, so he might be out of the running.
