Whats up with people trying to justify the level of evil here.
The Joker isnt someone whos supposed to be that likable. Dont justify it at least. At leats acknowledge that he's a murdering scumbag and state that you like him for the humor or whatever.
He would kill you, he would kill his friends, he would rape women, he would kill children, he doesnt care. He is a scumbag. I love how people think that he can kill tons fo people but if he kills children "hes totally evil!"
That was pretty much the point of Azzarello's Joker.
...And does Mr. Goddanm Batman says so much as ''Thanks''? OF COURSE not. That'd hardly be GRIM AND GRITTY, would it?
