Mike brought up the first one that came to mind for me. Xavier making the decision to switch off Magneto. That was a pretty memorable situation.

There was one in the New Universe where Star Brand encountered an American, who had been made indestructible by the White Event, trudging in the direction of Russia (I think it was Russia). When he realised that the guy was on the warpath, he tried to stop him with reason, then by force, and eventually he exhausted his options and did something like throw the guy into the sun. He wasn't killing exactly, but it was practically the same thing.

Strikeforce Morituri. The scientist who put the kids through the Morituri process was often tortured by the knowledge that by giving them powers she was shortening their lifespans to months.

The Darkness was an interesting aside to the anti-hero story, and occasionally wound up being the kill or not to kill dilemma in reverse. The central character is a ruthless and cold-blooded killer, cursed with a dark power that should make him even more evil, so he basically raises his middle finger to his dark heritage and starts using it for slightly more honourable reasons.

Tomb of Dracula running into an X-Men story. Rachel van Helsing's vampire hunting night life came to an end when she allowed Wolverine to kill her. The old, "I must die, it's the only way," trope.
