I don't know. When I did my Euron reread, I was disappointed at how much of his supposed creepy badass deeds were all related secondhand or done offstage, in a Darkstar kind of way. There's no real demonstration. Yes, people are afraid of him, but they're afraid of Roose too, and he DOES freaky stuff in public. I still like the character, but he needs to do something horrible in the next book.
