The 21st season of The Bachelor is here, and that means a whole new slew of contestants to get excited about. While we already have our favorites picked out for Nick Viall, there are bound to be some villains this season as well. Heck, the new bachelor was once a TV villain himself! In honor of season 21, we've rounded up the worst of the worst — or should we say the best of the best? — villains to ever appear on The Bachelor or The Bachelorette. Take a trip down memory lane as you reminisce on the men and women that made America cry, scream, and yell at their TVs.
