[DC] Have there ever been times DC heroes have killed without becoming horrible monsters?

It seems that in nearly every single timeline, whenever a DC hero kills for any reason, they end up becoming bloodthirsty and often tyrannical shells of their former selves who mercilessly slaughter everybody for the smallest offenses, or for even so much as whispering unkind words about them, and it seems like the League treats this is an absolute guarantee, without negotiation and compromise.

With that, has there been a time where the heroes have killed without this happening to them?

Wonder Woman killed Maxwell Lord. The rest of the Justice League wasn't exactly thrilled about this, but they eventually accepted that she was right and at no point did she become a bloodthirsty tyrant as a result. 

Green Arrow has killed in several timelines, either as a last resort or by accident. 

Superman executed General Zod, Quex-Ul and Zaora by exposing them to kryptonite. He doesn't talk about it and he's not happy about it, but they were genocidal.
