The significance of man’s role in Creation is immense.
When the day comes that we free ourselves from the overwhelming temptations to sin, the entire system of evil will fall back into its proper dimensions.
Those aspects of it that came into being as a consequence of man’s deeds—the ephemeral destructive angels—will disappear, while the eternal structural elements, which now serve as deterrents, will assume a new, entirely different role.
That which now appears to be evil will be reintegrated into holiness.
–Rabbi Adin Steinsaltz
