There are examples who work, you just need the right talent to pull it off. Hannibal Lecter, Judge Holden, Johan Liebert are the ones I personally like, but they work because of how genuinely creepy they are.
Joker sucks, though. Joker has never been even mildly scary no matter how much they edge him up, so all these attempts to make him "the most dangerous man who ever lived" are incredibly stupid and annoying.
Frankly I'd take "villain sues" over "the narrative tells you they're super heckin' geniuses, and then get easily outsmarted and beaten like idiots" villains. Those are the absolute worst.
