Harley Quinn is a mentally ill woman in an abusive relationship with a mentally ill man that doesn't care about her and only uses her as a tool and for sex
Jinx is a mentally ill woman with survivors guilt and PTSD who got adopted by a somewhat mentally stable criminal who tries his best at raising her, but fails due to his own inability to set boundries.
The only thing Harley Quinn and Jinx have in common is that they both display the "Mentally ill character has low inhibition for violence and laughs a lot"-trope, which is a staple of screenwriting for decades. Fuck you
