I'm just bothered by how unoriginal the Sims 4 are in how they react to things, despite their 'personalities'. Like, I have created an evil Sim but he acts the exact same way when greeting people, when flirting with people etc as the nice guy. Occasionally there's a stupid Mr Burns animation to "remind me" that he's evil.
I am not smart enough to figure out how I'd rather have them behave, but I've been playing a lot of DnD and perhaps a "chaotic neutral" "lawful evil"-system could inform the AI how to act in certain situations.
