Clearly there are fundamental differences between borderline personalities and sociopaths, differences which I appreciate. At the same time, when the borderline personality’s rage or desperation is evoked, one sees (and not rarely) responses that can closely correspond to the sociopath’s calculating, destructive mentality.
Once inside this mentality, I’m suggesting that borderline personality-disordered individuals can lapse into a kind of transient sociopathy. Commonly, victims of the “borderline’s” aberrant, vicious behaviors will sometimes react along the lines of, “What is wrong with you? Are you some freaking psychopath?” They will say this from the experience of someone who really has just been exploited as if by a psychopath.
Because this isn’t the borderline personality’s default mentality (it is the sociopath’s), several psychological phenomena must occur, I think, to enable his temporary descent into sociopathy. He or she must regress in some way; dissociate in some fashion; and experience a form of self-fragmentation, for instance in response to a perceived threat—say, of abandonment.These preconditions, I suggest, seed the borderline personality’s collapse into the primitive, altered states of self that can explain, among other phenomena, his or her chilling (and necessary) suspension of empathy. This gross suspension of empathy supports his or her “evening the score” against the “victimizer” with the sociopath’s remorseless sense of entitlement.
"The Borderline Personality as Transient Sociopath"
So. What do you think of Becker's ideas about borderline personality and transient sociopathy?
Do admissions (like my own) of a borderline breakdown that blurs lines between crazy-borderline and crazy-sociopathic risk further misidentifications of and biases towards the borderline personality?
Has your borderline personality ever threatened to trade hats with its sociopathic best friend?
What are we to make of this intersection of diagnoses?
