so let me play devils advocate for a second here. lets say theres an abusive situation and a person needed to leave that situation and never look back. then the psychopath goes around gaining fake sympathy from people looking "abandoned," when in fact, they were an abusive person who may have well killed the victim?

this is a tricky situation because then we go into the trauma triangle (or drama triangle, whatever one you wanna call it). There's 3 roles. Victim, perpetrator, and rescuer. A person can be any role at any time. An abusive person may hit their spouse at home and then go to work and be a victim to their boss. They may try to make up for their abusive behavior and try to "rescue" the victim. The victim stays in the victim role saying "poor me i deserve this im s alone everyone always leaves me" and will always feel helpless and seek out a rescuer. The victim may also become a rescuer or an abuser at any time also. A rescuer will sacrifice his or her energy into helping the victim except they're really just sending a message to the victim saying "you can't help yourself" and in the process they're losing a a part of their self. Once you have awareness of these traits in unhealthy relationships and families etc, then you can move beyond them and avoid unhealthy attachments and abandonment issues (in my belief). Here's a good site explaining the drama triangle a bit.
