He is the most ruthless of the villains, because he has no heart. Not only does he trick Charming, but he curses Snow White, kills Charming's mother and dares to tell Snow White that he was in love. The priorities of King George are possibly even more screwed up than Regina and Rumple. The difference between him and the two main villains involves caring for someone and making wrong choices about it. Both Regina and Rumple act, believing that they are protecting or avenging someone they love, but King George acts like a blood thirsty man with no priorities.
