Not a movie but Arcane s1.

Silco wants the undercity to govern themselves because the wealthy elites of Pilotver can't be bothered to care about the people down there. Every time there's an uprising it's beat back down with police force and the cycle continues.

It's fantastic because when he's first introduced the writers play on stereotypes to make you think he's just a run of the mill villain with a weird facial feature. No, he's trying to achieve revolution.

Not to say he doesn't do some fucked up things to achieve this dream. But that's why he's an actual villain not just a misunderstood good guy. One whose motivations make complete sense.
