Of course he wouldn't approve of killing unless absolutely necessary.

Its the reason why he became Ironman in the first place... he didn't want terrorists using his weapons to kill innocent people.

Sure, not everything he did is justifiable, but he certainly doesn't kill

@Adityathegreat You're joking, right? He killed numerous people as Iron Man. Hell, the reason his friendship with Steve was damaged was because he wanted to kill Bucky. Obviously he wouldn't kill innocent people but he definitely doesn't have problem with killing his enemies, even the ones he didn't have to like List

Can we stop complaining about what other people think for two minutes please
