That's DC comics. I meant among us. A lot of fans who didn't like stuff like DCEU Batman killing aren't fond of an overly brutal Batman who tortures people in general.
He'd still abuse the other heroes too. I have no faith that it wouldn't still be a shitshow all around.
We should be subtracting stuff from the bad stuff he does as DC ruins his character, not add to it.
One of the things about the films being designed to end is that it works for the villains going to jail and never escaping and/or being reformed. The Phantom Zone criminals in MOS for example got sucked back in and it doesn't seem like there were any plans for them to ever get back out again, unlike the recurring extinction level threat they always pose in the comics.
Killing Zod was an even more useless decision: if he got pulled back into the PF, he'd likely never return anyway because films are a finite narrative.
