I, for one, never that thought Walter White was "evil." He certainly veered that way over the course of BB, but he did what he did to help and protect his family. Ramsey does what he does for.... what? Fun? Kicks? To get an erection? And didn't they already have that character with Joffrey, Meryn Trant, and Gregor Clegane? How many sociopaths are there in Westeros? There's only, like, half a million people on the continent!
