As a non-expert in the field, I think she is a straight-up borderline personality disordered individual -- she is the very definition of BPD. And there are a lot of BPD symptoms that overlap with other personality disorders.
Likely true that she won't kill again unless she fears abandonment/loss of love object. Most of her whacky behaviors are related to her intense feelings of being betrayed by someone who is supposed to love her.
But any "future dangerousness" expert will have to point out that Jodi will perpetually be pursuing love attachments -- and will perpetually fail. Such expert would also likely opine that personality disorders like this are pervasive and life-long with little hope of improvement in someone lacking insight and lacking motivation to change (and Jodi lacks both of those things).
I'm looking forward to the psych testimony.
