Manipulation and unhealthy dynamics that don't involve forcing someone to question their reality? Blackmail, questionable moral arguments (that the villain believes in, rather than just something they're just saying to corrode the other person's sanity), dragging them into doing bad things, deals with the devil, "I know this is wrong but I have to for [reason]", falling in love despite knowing exactly what the other person is, in too deep, ect.

I've got that same DNW and regularly get darkfic, so it doesn't seem to put everyone off. Granted, I also prompt what I do want.
