If you really want to see an evil Batman, read Frank Miller's All Star Batman and Robin. That take on Batman makes the one in Batman v. Superman look positively gentle.
"Oh, you can’t help that," said the Cat: "we’re all mad here. I’m mad. You’re mad."
"How do you know I’m mad?" said Alice.
"You must be," said the Cat, "or you wouldn’t have come here.”
- Lewis Carroll, Alice in Wonderland
