"I began to think of war, even so-called "good wars" like World War II, as corrupting everybody. Violence begetting violence. The good guys beginning to act like the bad guys. And when I studied the history of wars, it seemed to me that that was the case. Athens vs. Sparta in the Peloponnesian War. The Athenians presumably the democratic state. The Spartans the totalitarian state. But as the war went on, the Athenians began to act like the Spartans. They began committing atrocities and cruelties. So I saw this as a characteristic of war, even so-called "good wars.""
