In the Brothers Karamazov, a little before the Grand Inquisitor section, Dostoevsky describes the death of an eight year-old, and this is sufficient to cause Ivan in the novel to reject the whole notion that a good God made the world. If I recall, the child accidentally hurt the paw of the dog of a rich man, was hunted down for it, and lifted onto a bayonet in the presence of his mother.
This sort of existential horror is too much for Ivan to hold together with the idea that a good God exists–and now multiply that by 6,000,000.
So I have a question for anyone who wants to answer it: if humanity goes on for another 10,000 years, and in each century there is a Holocaust-level horror (death by torturous degrees for a whole mass of people–akin to Dostoevsky’s eight year-old with his mother, multiplied by 6,000,000), would you still say that God’s creation is good–or would you say that you would have done it differently?
Could you will such a playing out of history–the Holocaust in reruns–or would you switch off the cosmic television set?
