One question that gets brought up to challenge any moral system is rather, if given the chance, you would kill Hitler as a child to prevent the Holocaust. Now, apart from any consideration of the grim consequences that might arise from this act, this simply shows a disturbing trend in our philosophy. Note that the question does not say "What would you do if you had access to Hitler as a child?" No, it simply asks would you kill him. The thought experiment jumps straight to murder. The problem creates a dichotomy, a strict dichotomy, and teaches us to think in fixed terms, making it out that there are only two, utterly grim options. But how often does life really boil down to this kind of simplicity? How often are there really only two choices? I suggest, that with a better developed moral imagination we might think of far richer solutions.
So what if you had access to Hitler as a child? Why not redeem him? Why not do the things necessary to make the man Adolf Hitler grow up to be a good man? A man of justice and equity. Imagine a man of Hitler's charismatic powers working to make the world a better place. Now, you might think this impossible, you might say that evil was Hitler's innate nature, and that he could have been nothing other than what he had been. That may be the case, and I'm not going to get into an argument here about determinism, that's beside the point. What is the point is that we didn't even think of it, and that is a moral problem on our part.
