Justified Revenge

Swift-footed Achilles, with a scowl, replied. "Hector, I cannot forgive you. As there are no trustworthy oaths between men and lions; as wolves and lambs share no common heart — they always sense a mutual hatred for each other - in this way, there can be no love between you and me, till one or other of us falls, glutting with his blood Ares, the god who fights under the shield's guard. Remember every valor of yours, for now the need comes hardest upon you to become a spearman, a fearless warrior. There shall be no escape for you. Pallas Athena will soon destroy you on my spear. You will pay in a lump for all those sorrows of my companions you killed in your spear's fury."

- Homer's Iliad, Book 22
