I think I understand the DT's (read CMJA's) argument.
Travis was a pedophile and an abuser who loathed that part of himself so much he wanted to die. He pushed CMJA until she broke and gave him what he thought he deserved.
CMJA was horrified because she was big hearted and kind enough to forgive him for what he was, because he had a good side too.
If she can forgive him, so should you the jury forgive her for killing him, because the murder represents her bad and mentally disturbed side which Travis made worse, not who she really is.
