Oh my God, Darth Vader is a total BPD! Good one, CN!
Childhood abuse, feeling protective of his powerless mother, never forming healthy attachments with anyone, being constantly rejected by his father figure (Obi-Wan) because of the Jedi code, finally giving in to his rage and ruining his life and of those he loved because of it - and all for love and the anxiety of losing it!
Then there was just the emptiness, hatred and the need for acceptance on a new father/mother figure who abused him and gave him the distorted attachment bordering rejection, shame, abuse and pain with promises of love and absolute loyalty.

I'm sad now, poor Anakin.
I'm trying to dig up the statistics, but there are usually less ASPD and psychopathic inmates than BPD inmates. Found a study that shows the percentage of people who are in prison having BPD being higher than in the community, but seems shady and it's not what I wanted from this thread.
I actually wanna know if BPDs can just have attachment and emotional dysregulation issues without necessarily sharing the, as Casper put it, "malicious" traits (the traits that are usually found in NPD, HPD and ASPD).
And please, this is not an inflammatory thread. I know BPDs have difficulty discussing their illness unlike any other diagnosis (aside from some schizophrenics who seem to get very upset when you disagree with the veracity of their hallucinations or just say they're disordered - those get ANGRY!). I really just want to see people who actually have issues outside of the malicious, violent and aggressive BPD traits. I just wanna know if it's inherit or not.
Maybe it would have a lot in common with codependant PD.
