 We had a religion professor who posed that ethical question that apparently it's a tired old trope. It might have been new back in the 70s, but it was called the baby Hitler conundrum. If you saw a baby and you somehow knew, you were assured, you were absolutely promised that baby was going to grow up to be Adolf Hitler, murder six million Jews, and just be one of the most vile, murderous animals on the planet, would you be justified in killing that child? And I remember we debated this stupid academic argument yesterday.
