The notion that the [Joker] is 'criminally insane' was given more depth in the Steve Englehart and Marshall Rogers run in a 1978 story entitled 'The Laughing Fish' ... which combined a deliberate reworking of the Joker's original 1940s appearance with a severely demented personality. To date, this issue remains one of the best portrayals of the character's madness. [...] From that point forward, the Joker was always depicted as being ... batshit crazy.

By 2007, the Joker was indisputably one of the most dangerous and insane villains in DC's entire universe. This is evidence in the 1995 three-issue Underworld Unleashed, in which Flash-nemesis the Trickster said, 'When super-villains want to scare each other, they tell Joker stories.'

[The Joker] also seems obsessed with Batman, as if he were incomplete without the presence of Batman in his world, and is the moral opposite of him when it comes to his goals: While [Batman] and his allies strive to protect the people of Gotham, the Joker seeks to kill, maim and torture them. The two are always at war and are, in many ways, the antithesis, that defines each other's existence.
