KC had been basically begging for boundaries all her life. "I should've been stopped a long time ago."
respectfully snipped.
I have a different view of this. I don't believe Casey begged for boundaries. I believe these words project responsibility for her actions on to others.
There is no doubt that Casey Anthony is personality-disordered. I do not believe she has BPD, though BPD certainly shares some features with antisocial personality disorder.
She is conscienceless. Her post-crime behavior has not been typical of BPD, but rather of APD/sociopathy. She does split and manipulate--but sociopaths are skillful at this, as well. Her thought patterns are too organized, IMO, for BPD.
Casey can handle boundaries perfectly well. She's handling jail just dandy.
But when push comes to shove, and she has the ability NOT to handle the boundaries, she won't---and she will do as she pleases without a thought to consequence. She tramples those around her with no thought to the effect, unless the effect will somehow influence her.
I am grateful for your insight, April--and also glad you're doing well. And I can definitely see the parallels you drew. But I think there is far, far more to Casey Anthony. (Or, rather, far less. I think she is far less. She is base and evil.)
I think we want to humanize her more so that we can understand her. But you can't understand the inexplicable, other than to say she is lacking humanity. And the diagnosis that that fits isn't BPD.
