Shakespeare is great for this: Iago, Aaron, John the Bastard are the ones that come to mind to me, but I'm sure there are more! Richard III probably counts as well.
The Enchanted Forest chronicles has the Right Honorable Wicked Stepmothers' Traveling, Drinking and Debating Society, of whom the most notable member is Uncle Rupert (Gentlemen's Auxiliary for Wicked Uncles.) Sadly they are not led by an evil horse.
Some characters from DWJ's Dark Lord of Derkholm might count too. As actually might Tacroy from Lives of Christopher Chant and Charles from Witch Week. Oh, and Howl-the-genie in Castle in the Air.
