do you mean killing? If so he kills in pretty much every movie. And the source material as well. I can understand the shock over superman(killing), but that cats out the bag already anyway.
Here he is in batman returns lighting folks on fire(he likes to do that). I don't recall the exact number but I think it was 3 people he killed in this 5 second scene.
Then this is from a 2007 or 08 comic. Lights a half dozen people on fire again.
Or an early comic. He killed hundreds of people in the 40s.
Or maybe it was just an accident(a couple hundred of those over the years too. Or he just didn't save them. Like with Ras in batman begins..
Or a little more personal. And with a smile!
He fights a strong man, hits the guy. Guy smiles. Batman smiles and dude looks down to see batman put 3 sticks of dynamite on his chest. And as the guy on forged in fire says...that will killl
Here's more of those early days. Killing all those pesky Asian folks...
Or Darkseid. (Or at least trying)
Then there's the run in "year two" where he runs around shooting people with the gun that killed his parents. Or when he locked a guy in a sewer to starve to death.
