We're attributing killing Batman to wokeness?
By that token, wasn't Zack Snyder woke for killing Superman? Or was it maybe that he's an edgelord thinking that he's mixing things up by killing off the most recognizable characters in the world?
After all, this game kills John Stewart (one of two major Green Lanterns that just happens to be black) and strips him to his underwear, also having him beef with the only other black guy in the game for no discernable reason other than the preconceptions of devs who probably think themselves "woke". It even kills off that androgynous Wonder Woman interpretation without much ceremony.
Point is that reason would suggest that killing off Batman and the rest of the Justice League was a case of shock value many many years too late. When people were going off about how Rocksteady was shitting on Kevin Conroy's legacy as if they planned for him to die in the 7+ years this game was in development or some shit, it just sounded stupid.
When you're the leader for 6 out of 7 years of development, you're going to get a disproportionate amount of the blame.
I don't know what percentage is accurate for that, but cmon.
