I got a game recently where you play the begrudging assistant of the bad guys. It's one of the few games where going with the outright evil choices rewards you heavily.
I can't bring myself to do it.
If you're not opposed to an adult game with some problematic elements, Seed of Chaos. I honestly got it for the obvious reasons, before realizing I like the story and gameplay loop more than the stuff I bought it for.
Seeds of Chaos is a dark fantasy eroge made in Ren’py, inspired by the worldbuilding of Berserk, Dark Souls, The Witcher and other epic fantasy series, as well as the adult games Corruption of Champions, Legend of Queen Opala, and Slavemaker.
