When you have age after age of the human race rejecting the provisions and teachings of each of the Divine Beings revealing a new Revelation for mankind, you slowly create a human race with a culture which attracts the heart away from God (towards evil).
This does not mean that the human heart is not made in the image of God. It is. It just gets sullied by the evil inclinations of a ravenous societal culture borne out of rejecting God.
This is an outcome of our free will which is an essential element of our being made in the image of God. A God who also has free will.
