I don't think it would change him. Derek "killed Jackson with Peter in S2 and he was far from innocent. He remained an Alpha. Since I can't imagine Scott killing anyone unless they were guilty and needing to be put down, I don't think he'd lose his spark by dealing the killing blow if he had to.

I do agree with that theory of him and how he views himself, and how that affects his power. Maybe he wouldn't be himself. But he talked to his dad about when he had to kill people as a cop, during the Deadpool storyline...and he told Stiles that he understands the difference between murder and self defense. SO I think it would be fine.
