"The portrayal of Batman presented here is not definitive and is not necessarily how I would write the character otherwise. The repressed, armored, uncertain and sexually frozen man in Arkham Asylum was intended as a critique of the '80s interpretation of Batman as violent, driven, and borderline psychopathic. My own later portrayal of Batman in the JLA comic was one which emphasized the character's sanity and dignity."
