For those worried BPD is a mitigating factor, I can assure you it is not. Provided the jury gets (and understands) a good explanation of BPD, which I trust Dr. Demarte has and will continue to provide along with Juan, they will not see it as mitigation.
How can I insist on this? My mother has BPD. She was a single parent and I the only child, so I've directly experienced so many if the BPD behavior manifestations. In my early 30's BPD was explained to me by my counselor because through our sessions she concluded my mom had BPD. At first I didn't believe it, but the more I read and the more she educated me I realized my mom definitely has BPD.
My mom knows right from wrong, but she justifies her behavior when it's wrong using a variety of ways common to BPDs, like playing the victim and situational ethics (i.e. it's okay in this situation because xyz). CMJA knows right from wrong too, and her BPD doesn't make it any more difficult than anyone else to refrain from murdering someone. It only makes her better than the average person at playing the victim and applying situational ethics to justify her unjustifiable behavior (brutal murder).
If my mom were to brutally murder someone, which I'm fairly sure would never happen, I would not be able to say her BPD mitigates her actions just as I've asserted in regard to CMJA. Similarly, I've learned through my counselor that my mom's BPD doesn't mitigate her poor parenting and neglect of me, it only explains that it was the best she could do at that time...but she could have sought help. BPDs know something isn't right with them, they know their behavior isn't normal. This makes them responsible for not getting help. Failing to seek help for a psychological disorder that you cognitively know is present is not a basis for mitigation.
No mitigation = Death Penalty
This is the AZ law, therefore I believe CMJA should be sentenced to death...even though I would prefer a special sentence of LWOP with special conditions that give her very little access to other people. Kind of like solitary, but a bit less cruel, because I think having little tastes of it will help remind her what she will never again have.
My mom is also BPD, and not diagnosed till she was 65. She had been in counseling, seeing psychiatrists and on many meds since I was a child, but no one ever dxd her. I remember when she told me. She was really miffed, insulted. Now I know why she was what I deemed "crazy" as a teen. She would have outbursts one would expect me to be having at that age. But, like you, I realize now she did the best she could at the time.
