Doesn't it seem more likely that he would have narcissistic (as well as psychotic) rather than depressive personality disorder? I think he would have to be incredibly arrogant and confident in himself to do this in broad daylight with 2 victims, especially if he is from this small community and would be easily recognized. I think he has complete lack of empathy and therefore a lack of guilt. I don't think he is concerned with any of this sort of thing referenced in the PC. He killed these girls to fulfill his needs with no regard to anything else.
I appreciate your thoughts. It’s hard and frankly impossible to diagnose him as it could be many different things ...however I see the severity of the mental illness as more than a personality disorder. Major depression with psychotic process is not a personality disorder. That’s why I said “severe mental illness such as...”. In MOO there is some sort of psychotic or delusional thinking process that occurred.
