In certain religious contexts, evil has been described as a supernatural force

6.Is there such a thing as Original Sin? What does it mean either way?
Original sin is the Christian doctrine that humans inherit a tainted nature and a proclivity to sin through the fact of birth.Theologians have characterized this condition in many ways, seeing it as ranging from something as insignificant as a slight deficiency, or a tendency toward sin yet without collective guilt, referred to as a "sin nature", to total depravity or automatic guilt of all humans through collective guilt. Augustine (354–430) first shaped the doctrine of original sin.[3][4] Tertullian (c. 155 – c. 240), Cyprian, Ambrose and Ambrosiaster considered that humanity shares in Adam's sin, transmitted by human generation. Augustine said that free will was weakened but not destroyed by original sin.[4] Augustine's formulation of original sin was popular among Protestant reformers, such as Martin Luther and John Calvin, who equated original sin with concupiscence (or "hurtful desire"), affirming that it persisted even after baptism and completely destroyed freedom to do good and proposed that original sin involved a loss of free will except to sin.[5] Modern Augustinian Calvinism holds this view. The Jansenist movement, which the Catholic Church declared heretical from 1653, also maintained that original sin destroyed freedom of will.[6] Instead the Catholic Church declares "Baptism, by imparting the life of Christ's grace, erases original sin and turns a man back towards God, but the consequences for nature, weakened and inclined to evil, persist in man and summon him to spiritual battle."Weakened and diminished by Adam's fall, free will is yet not destroyed in the race."

St Paul's idea of redemption hinged upon the contrast between the sin of Adam and the death and resurrection of Jesus. "Sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned."[Romans 5:12] "For as in Adam all die, so in Christ all will be made alive."[1 Cor 15:22] Up till then the transgression in the Garden of Eden had not been given great significance. According to the Jesus scholar Geza Vermes:
Paul believed that Adam's transgression in a mysterious way affected the nature of the human race. The primeval sin, a Pauline creation with no biblical or post-biblical Jewish precedent, was irreparable by ordinary human effort.[9]

Augustine claimed that the doctrine of original sin was first taught by Irenaeus, the Bishop of Lyon, in his struggle against Gnosticism.[4] Irenaeus contrasted their doctrine with the view that the Fall was a step in the wrong direction by Adam, with whom, Irenaeus believed, his descendants had some solidarity or identity.[10] However, Irenaeus did not believe that Adam's sin was as severe as later tradition would hold, and he was not wholly clear about its consequences.[11] While the belief that all human beings participate in Adam's sin and share his guilt are not totally foreign concepts for Irenaeus, still his doctrine of Original Sin is rather mild compared with what would later be found in the writings of Augustine. One recurring theme in Irenaeus is his view that Adam, in his transgression, is essentially a child who merely partook of the tree ahead of his time.[12] For Irenaeus, knowing good and evil was an integral aspect of human nature; the "sin" of Adam was snatching at the fruit of the tree rather than waiting for it as a gift from God.
