Dr. Truman and Pratt in “Atonement”

Why? Why would God do that? Why would he have me kill 17 people to save one?

Pratt

We may not understand it, but that little boy is alive because you were there! Now, whatever you need that to count for, it counts!

[takes a long pause, then shakes his head and buries his face in his hands] It doesn't make sense.

Pratt

[places his hand gently on Dr. Truman's shoulder] It doesn't have to make sense. That's why it's called faith.
