Must. Contain. Rage.
You’re an idiot OP. What fucking right is it of ours to end someone’s life? How do they not have a right to live? If you really wanted to punish someone, you’d let them live with the guilt of killing a fellow human being.
And you can’t reverse death. What if that person you killed ends up being innocent? What then? Do you just magically go back and not kill them. OH THAT’S RIGHT YOU CAN’T.
