It was after Batman got Joker off that I stopped caring about him, his notion of "justice" and whatever self-righteous morally sanctimonious drivel he is supposed to uphold.
That's not to say this story wouldn't have worked - if it had been any other criminal besides Joker. Or Zsas. There is sincere belief in redemption and then there is sheer utter blind stupidity.
What about the hundred of Joker's victims, past, present and to come, damn it? Where's the justice and protection for them?
