An important (and fun) part of adapting villains in a Human Au is making them humanly awful. Like, they're probably not going to be violent on the daily (without consequence at least) but they've gotta maintain their villainy/nasty vibe somehow.
So, you gotta think to yourself "how would this character vent their insecurities/frustrations at the expense of others?" and work from there.
Needless to say I've been thinking about these idiots a lot.
