Out of touch with reality, since the Joker thinks he is unreal, qualifies Batman as psychotic obsessed with revenge. It's the Joker that's simply evil mainly because he's continually pursued and aggrivated by Batman to avenge his parent's deaths which as I say might have been handled normally through the proper channels in the courts. Instead he goes on a vigilante avenger type manhunt that makes and forces the Joker to possibly be worse than he would have ever been otherwise - a super villian evil nemesis in response all for the sake of Batman's insatiable personal revenge.
That assumes the Joker is a reaction to Batman or that the Joker killed the Waynes. The latter is only true in Burton's film. In most other versions the Waynes are killed by a two bit nobody armed robber named Joe Chill.
