Okay so in Three Jokers there's a scene where Batman kills the poor guys that have been kidnapped and jokerized it's when he's looking for Jason and he and Barb find all these guys turning or being in a messed-up state. One guy actually goes "Help me." I think and the reaction from Batman and Batgirl is one that results in the deaths of these men who have all probably been kidnapped and tortured by Joker. Jason's particular reaction upsets me as well he shows no empathy to these victims just wants to kill all the Joker's I mean seriously what if one escaped but retained his sanity would Jason still want to kill a guy just because he looks like the Joker? I have the same issue with what's happening in The Man Who Stopped Laughing. Jason is chasing a man who Batman says isn't Joker. I feel it's more than likely neither Joker is real and Joker's just watching everybody make fools of themselves while getting a new eye or something.
My point is that I'm surprised innocent people being harmed, mutilated/disfigured, dying and not being saved by the Bat Family just because Joker made them look like him is something that should be addressed in a future story. Another thing I'm bothered by is Harly thinking the one Joker is a fake because she doesn't think he'd show up to her. Joker's whole thing is that he's crazy. So, I find it weird she's even surprised by him doing the bizarre. The multiple Joker thing also makes me question if Harley has even met the "real" Joker.
