One of the things that stuck out to me about the Animated Series incarnation of the Mad Hatter is that he genuinely blamed Batman for all of his actions. He made it a point to mention more than once. He said it in a good chunk of his appearances, starting with his first. Even in Trial, he was one of the only rogues questioned aside from Harley and Ivy. I'm actually surprised they didn't delve into it more (or it didn't carry into comics).
