I don't think there's anything wrong with feeling sorry for Jodi. She is disordered, and it's not like Jodi chose to be BPD. What's really sad is that there was no intervention for her before it got to this point.
I have some compassion for her also. Nevertheless, I think she should be found guilty of 1st degree murder and sentenced appropriately.
You're a better person than I am. I feel no compassion whatsoever. She's been an adult for a long while, has to have known she was not OK, and did nothing to help herself, ever. Nope. Her decisions, her choices, her responsibility, her consequences.
