Byrne had him do it, and it had serious psychological consequences to the point that Supes vowed never to kill again.Cyborg Superman doesn't count, because Supes already knew Henshaw could survive without a body, and Doomsday from Superman/Doomsday was just another marketing gimmick tie in to Death, and also out of character...
The exceptions prove the rule, and there's far more proof that Ending Battle is how Superman normally acts than not.
Just because Batman used guns in his earliest appearances, or in Final Crisis, doesn't make that normal for his character..
I'd agree that it's unlikely that Superman would kill under normal circumstances; Ending Battle (at the time) was pretty accurate, I thought. I also felt, though, as time went on Superman changed a little. Not much, but enough to the point that if you pushed him far enough, he'd do it. I'm not saying it's easy to get him that far, but i think it's possible.
I wouldn't say that Batman is a killer either, but writers have slipped up on that end too. Not as much in the last couple of decades obviously, and he's now the most severe case I think.
