Just to lay this out here to give you a slight frame of reference that you can think about how various cluster B 's appear to act on the surface:
Casey Anthony was not affected by her daughter being gone. That's why she gave us that inappropriate, hideous, smile in the courtroom, and why she was smirking when she got arrested, plus a whole list of other odd behavior. She is a sociopath, not a borderline, histrionic, etc., but a sociopath like Dexter/Hannibal Lector/BTK/Ted Bundy, etc. That's what we're talking about here with Casey Anthony as an example. Someone like a teacher that screws her students well, that's a histrionic. Someone like Amy Winehouse, that's a borderline with severe ASPD.
