I have watched this movie more than once, Truely Truely an emotional stirrer. I loved the use of bible verses to depict the characters as hero's despite being very rough on the edges and sinful they were still fighting the evil German Nazis who were killers and oppressors of many people. Norman who was the merciful one who was shown mercy in the end.
If you forgive others your sins are forgiven and by the same measure that you judge that same measure will be judged back to you, That's why Norman was shown mercy by that German solider in the end.
I loved how characters you disliked in the beginning you later learned to understand.
