Setting aside the various performances of the Joker in past and future incarnations, does it strike anyone else as self-defeating to have him be such a central focus of the PR campaign? I mean, the Joker isn't even on the Squad. He never has been. He shouldn't be in this, either. The Squad is a great concept -- a comic book Dirty Dozen -- but the Joker isn't really the "joining" type. He's too insane to be reasoned with. The guys on the Squad can sometimes be insane, other times cowardly, and almost always self-interested, but it's that self-interest that folks like Waller count on -- to give the Squad members a reason to go through with their activities. You can't count on that with the Joker. Actually, you can count on the fact that he's bat**** insane, and therefore probably won't be motivated by self-interest. Plus, unlike, say, Capt. Boomerang or Deadshot, Joker is a criminal mastermind and letting him go -- even for a minute, even on a mission -- just invites him to escape and then become a far greater menace to the public than either ever were.
