If we own the story then we can write the ending.
Is it possible that the relationship between humanity and evil is similar to the relationship between the ocean and an iceberg floating on its surface? Both the ocean and the iceberg are made of the same material. That the iceberg seems separate is only because it is in a different form. In reality, it is but a part of the vast ocean.
