Actually, people don't know right from wrong as children. While most children develop a theory of mind (meaning, they understand that other people around them think and feel like they do), empathy != morality. It's the start of it, perhaps, but not the end result. That still takes reasoning.
Anyone that's actually been around children knows that they'll bite, scratch, fight for what they want, when they want it. Children are very territorial and inherently selfish, likely due to evolutionary factors ("No, that's my nipple, get your own!"). That's why a huge part of parenting is about instilling values and teaching children how to act properly in society. If they came out of the womb with any idea of morality, life would be a hell of a lot easier.
