I don't think anyone is programmed to live that way. But I get what you feel. Honestly it sounds like you're in a very precarious situation and if worse comes to worse than you ought to go get help, because as unpleasant as that would be it still be better than jail. Multiple people with MI in a close family is it's own kind of difficulty. And I would absolutely want to kick the ever living crap out of someone like that, because it reminds me of something I've got going on that's similar and I do. Feeling like doing it is one thing and then actually doing it is another. Your Evil One you called them, probably feels as terrible as everyone else, otherwise they wouldn't feel so strongly enough to want to plan anything, and maybe taking things from a perspective of empathy for them might work better than viewing them as an antagonist. I'm mostly saying that because we have one....or well I guess two in the system who are known for being like that and trying to understand them works a lot better than trying to tell them they're bad.
