Black Crusade has the players playing as Chaos (one of the "evil" factions in the setting, although none of the factions are exactly good , per se, except from their own point of view). Many of the World of Darkness games have at least some hint of evil in their characters. It's probably most apparent in Vampire, Wraith (the character's Shadow, at least), and Demon. Manual of Exalted Power: Infernals is one of the splatbooks for Exalted (second edition), and has the players playing as one of the fifty Green Sun Princes, exalted servants of the setting's hell-equivalent. A GSP's Yozi master can even punish him or her remotely if the GSP isn't committing "Acts of Villainy." (This is supposedly changing in the upcoming third edition.) The GSPs' overarching goal is to get their Yozi masters released from their prison. Similarly, Manual of Exalted Power: Abyssals (second edition) and Exalted: The Abyssals (first edition) are the splatbooks for playing as one of the 100 Abyssal Exalted, exalted servants of the Underworld. The Abyssals' overarching goal is to send the entire world into Oblivion, so that their Neverborn masters can either come back to life, or properly die. Finally, Graceful Wicked Masques (second edition) is the splatbook allowing players to play as Raksha (Faer Folk), creatures born from the chaos energies outside the bounds of the world. The Raksha, by and large, see the stable form of the world (and everything in it) as an insult, and would like nothing more than to completely unmake the thing.
