deranged

Though Bane’s sing-song voice gives his pronouncements a funny lilt, he doesn’t have any of the Joker’s deranged wit, and Nolan isn’t interested in undercutting his seriousness for the sake of a breezier entertainment.

When he was finally arrested, Sutcliffe hoped that by claiming to be deranged he would be convicted of manslaughter rather than murder, and therefore sent to hospital and perhaps released after 10 years.
