Perhaps, but OB is all from Anita's near-omniscient POV, which means that what Anita thinks can basically be said to be canon. And Anita thinks Edward isn't a sociopath, isn't some sort of psycho, no, she thinks Edward has Dissociative Identity Disorder, or multiple personalities. Ted is Ted and Edward is Edward. And he displays enough signs of this that if one were to take Laurell's usual half-assed research into account...well, it's probably true. Sociopaths aren't like that, they only embrace society and its ideals as much as they want. With everything that happened in OB Edward's pretty far from the true sociopathic bent and pretty far into the "truly crazy in a complete different way".
