10 Times “Good” Characters Gave Being Evil A Try
10. Theon Greyjoy
When it comes to someone like Theon Greyjoy, people either hate him or love that they hate him and it has everything to do with what this guy did. Sure, he was taken hostage as a kid by the Starks, but they treated him like one of their own children. He grew up alongside his “siblings” and even helped wage war in the name of the North… until he flipped the script and betrayed everyone around him.
Possessed by some strange loyalty to his horrid father, Theon captured Winterfell and fake-executed his two little brothers. Granted, he didn't kill his adoptive kin and instead slaughtered a couple of innocent farmboys, but that is only slightly less evil.
Just when it's starting to look like Theon won't reform, he's captured by Ramsay Bolton, who is arguably the most sadistic fiend in all of literature. He picks up the name "Meek," loses the family jewels, and learns the error of his ways via a strict regimen of torture and mental abuse.
Theon eventually redeems himself by helping Sansa escape Bolton, but his foray into evil was pretty costly and horrific, which just goes to show you shouldn't betray your adoptive family for your real one if you're a main character on Game of Thrones.
