This was me at Capital Pride last year. I was walking around dressed as Xena, posing for photos and giving hugs, when I noticed these religious zealots with their microphones and signs spewing their messages of hatred. I always ignore them, but I noticed they were making some people in the crowd visibly upset. A few people were even crying. I couldn’t stand by and let that happen. I hopped over his little chained off section and stood next to him. He immediately turned and began yelling at me and telling the crowd I was going to hell. So I just kept smiling and making funny faces. He eventually gave up yelling to me and about me and tried to go back to taunting people. But no one was taking him seriously with me standing there posing. I’m sure they will be there again this year….and so will I. :-)
Notice how the Joker has every reason to be killed by Batman in the DCEU.
We saw Batman kill. He already crossed that line. He doesn’t have the excuse of “it’d be too damned easy.”, he couldn’t make that speech to resurrected Jason, claiming that killing is bad when he did it himself.
And we know he attacked the Joker, he was the one to punch all the teeth out of his mouth for killing Robin, he fucking let him drown in the car chase scene in SS, when he took Harley out of the water and gave her CPR (which implies that Harley wasn’t actually associate in killing Jason, or else Batman wouldn’t save her.) the joker didn’t die right there because he was needed for the plot of one movie (and also he’s a cockroach who won’t die unless you shoot his head.)
Which brings me to the behind the scenes reasoning: people hate the current DCEU joker. In almost every other media the joker is stanned, people LOVE him. He’s so goddamn popular, DC can’t bring themselves to finally kill him.
But here? DCEU Joker is hated. The actor is disliked (to say the least) by his cast members, and the audience, and apparently the movie editors as well. It wouldn’t be a shame if he were to die.
TLDR; Batman kills in the DCEU. The Joker is a hated character. Make it happen, DC!
