I had two different quotes that kept popping into my head while reading this book. The first, from Edmond Burke, is: "The only thing necessary for the triumph of evil is that good men should do nothing." The other, from a YA Fantasy series I enjoyed, Daughter of Smoke and Bone by Laini Taylor: "It is a condition of monsters that they do not perceive themselves as such. The dragon, you know, hunkered in the village devouring maidens, heard the townsfolk cry 'Monster!' and looked behind him."
