Human nature as created is wholly good. At some specific point in the past, the ancestors of humanity misused their freedom, producing an inherited, congenital flaw in all of their descendants. The fall of Adam and Eve is a representation of a universal phenomenon. Each of us falls individually, and yet the falling is both inevitable and guilt-procuring. There is a mismatch between the natural needs of human beings and the artificial needs and desires produced by society, resulting in crime, vice, misery.
Evil is a necessary and inevitable phase in the development of the human personality.
It represents a step up from the innocence of nature and a necessary prelude to the achievement of virtue and wisdom. Sin results from the necessary and inevitable assertion of the individual against the universality of morality. The moralistic distinction between good and evil is fundamentally false. There is a universal tendency toward evil among human beings, and this is not due to changeable social conditions. The Fall is an event at which all of humanity acquired an unnatural but irreversible tendency toward evil.
