Why? But the count had been stopped from hurting Felicity with the first arrow and Oliver just did the others to murder him. And Oliver still had a hand in the murders of several security guards in russia, two security guards in starling and a man in nanda parbat, all who for all intents and purposes were regular people, not evil.Fincher said:Oliver didn't make some promise to/deal with criminals that he would never kill them. He made a decision to stop his general methodology of killing, and he held to it when he could. Which is exactly what he should be doing. If he'd let Felicity get murdered by Vertigo because he was never going to kill again, I'd probably have stopped watching.
God bless you! God bless everyone in your life!
