Darren Aronofsky's Noah, like the Book of Genesis, raises important questions about evil, God, and what a righteous person should do. Some of the details between the two portrayals differ, but the horror of genocide and its effect on survivors are not avoided.
Genesis uses stories, some with historical origins, to face hard questions. The book does not offer a consistent image of God. Rather it reflects the struggle of primitive societies to adapt to an unpredictable and dangerous world. When the Tigris and Euphrates rivers would flood, indiscriminately killing many, the survivors would ask "Why did God/the gods allow this to happen?" and "Why did we survive and not others?".
Earlier in Genesis, humans were created with a "you-can-choose" gene. In time, evil was the result. Yet the decision in Genesis 7 for the Creator to suddenly become, like the worst of humans, a mass murderer is truly shocking for the reader.
Dr Karen Armstrong writes: "At best, the God of the Flood can be seen to behave like a petulant child who is tired of the castle he's created with his building blocks and knocks it down. At worst, he appears like those tyrants and dictators in our own century who have assumed godlike powers and have attempted to purge the world of what they regard as evil."
Aronofsky raises the same theological issues. God is largely silent in the movie. At one point the key villain laments: "Why doesn't God talk to us anymore?". Why, indeed. Do you excommunicate and drown your children when they have the gall to grow up and disagree with you and make choices you don't like?
