Sin

The result of the fall of Adam in the garden of Eden with Eve causing both a physical and spiritual separation from God and the necessity for salvation to be redeemed. This is why death, disease, bloodshed, suffering, extinction, thorns and violent weather exists. As descendants of Adam all of mankind are inherently evil and subject to God's wrath and condemnation. For a child does not need to be taught how to be selfish, lie, fight with their sibling, commit theft, etc.
