The Harry Potterfranchise has plenty of villains to hate. The antagonists range from Hogwarts bully Draco Malfoy (Tom Felton) to the Dark Lord himself, each presenting a different challenge to Harry (Daniel Radcliffe). But, despite his crucial role, even Voldemort (Ralph Fiennes) isn't the worst the series has to offer. With antagonists like Umbridge (Imelda Staunton), whose self-righteous, sickly sweet attitude earns her a place among the most hated characters, and Fenrir Greyback (Dave Legeno), whose unique brand of violence is especially dark, it's hard to see Voldemort as the worst. He may be the central antagonist of Harry Potter, but Voldemort isn't the most evil character in the story. That honor goes to Bellatrix Lestrange (Helena Bonham Carter), the dedicated Death Eater, who, while not the leader of the organization, does the dirty work, unlike Voldemort himself.
