12) Ramsay Bolton

One of the most sadistic and crafty characters in Game of Thrones is Ramsay Bolton, played by Iwan Rheon. He was often successful in defeating his enemies with a combination of psychological warfare and direct aggression. He gains the trust of Theon Greyjoy by pretending to be a friend, only to brutally torture and break him, turning him into a loyal servant. Ramsay also secured his place as heir to House Bolton by eliminating threats like his stepmother and his half-brother. His cunning and ruthless machinations were the glue that kept his grip on the North.
