I agree. If he has a past history of behavior indicative of Antisocial Personality Disorder, that will be a disaster for him.
It has only been "proven" there was one affair, but there has been rumors of multiple affairs/serial cheating. If these rumors are true, there is a Cluster B issue, and my thoughts have always been ASPD, and that is because of the way he handled himself post murder (s).
I also hope the prosecution digs very deeply into his past for signs of this, and that they specifically dig into the hasty move to Colorado. If he is ASPD, he may have manipulated the move to Colorado to get SW to sell her NC home, thinking the sale of the home would bring a huge profit. This is exactly the kind of manipulation ASPD's are capable of doing to their victims, and their victims do not even realize what's really happening.
The house did not bring a profit, and she moved before she even sold it. If he is ASPD, in his mind, that would have been all her fault, too. They absolutely love to blame their victims, which he has done in his "confession". I expect more "blame" to come as this case progresses.
All JMO.
