Classical tragedy was the war between good and evil. We wanted evil to be defeated and good to be victorious. But the battle in modern tragedy is between good and good. And no matter which side wins, we'll still be heartbroken.
The most painful moral struggles are not those between good and evil, but between the good and the lesser good.
Christ shared our experience; he suffered as we suffer; he died as we shall die, and for forty days in the desert he underwent the struggle between good and evil.
Reducing everything immediately to good and evil is bad history - not only because it isn't true, but because reductionism is unpersuasive; it is boring. Good history, on the other hand, demands that one talk socratically - that one can present alternate viewpoints, not strawman arguments.

People's character is their behaviour - we're all capable of good and evil.
