Fucking hell.... that's a horrible story. That's a narcissistic sociopath/psychopath who has done a full BPD split and lost control of all faculties.

I stand by the fact that coercive control is remains as toxic, it is the psychological underpinning of this sort of thing. Given the biological predisposition to aggression in males - I take your point it's far less likely to escalate into something as tragic as this.
