Ra's and Oliver in “Unfinished Business”

I was 11 years old when I killed my first man. I remember the look in his face when the light went out behind his eyes. Such a sudden change, almost imperceptible, between life and death. And I felt ashamed. I had stolen from that man the most precious gift of all - life. But I also felt something else - pride, because I had taken up arms against someone who sought to do ill against my family. And I realized what I had done was necessary. You see... I had replaced evil with death. And that... is what the League exists to do. And I have killed several thousand more men since then. And the world is better for it.

Oliver

You've taken your last life.

No. . . . You have lived your last day.
