I do believe that Justice for Travis and his family is critical.
However, what we know of Jodi and Travis's relationship is only fragmented - and seen through the eyes of witnesses and emails years after it happened.
If I discovered that one of my son's was sleeping with an ex girlfriend, calling her names, talking nasty behind her back - while openly out there looking for a wife... well, look out kiddo - cause momma's comin and she's angry as a hornet.
That's just no way to behave. It's not worth killing over, or dying for - certainly. But when two people so completely twist a relationship into something really ugly - it can happen.
As for Sociopath - well, a number of psychologists examined her. There were 2 different diagnosis. Sociopathic personality wasn't one of them. And I believe the DMI includes that diagnosis.
If you accept Dr DeMarte's diagnosis - BPD - Jodi is the opposite of many things attributed to her in social media. Borderline's loath themselves. Not love themselves.
