Evil is the consequence of unredeemed human nature. By “unredeemed” is meant here a failure or refusal to accept the freely-given gift of redemption already won for us in Christ, because, primarily, of human pride. The imperfection of human nature chooses pride over love for God, even refusing, or dismissing, God’s plan for salvation, in favor of a worldview of one’s own making. This is an abuse of Free Will that leads to sins venial and mortal.
