And it's ridiculous to think that any given six-year-old may have committed a horrible act worthy of being executed unless the text says otherwise, just because that six-year-old has green skin and her parents bring her to their church services. That right there is enough reason for the story to be the way it is. No author should have to take the time to say, "This little girl ISN'T evil, folks!" in order for the reader to understand that. It should be assumed that no first graders are irredeemably Evil unless the text tells you they are.
