SEEn original sins has no biblical grounds. I believe that it was/is being used by the church as some sort of missionary tool too make people go to church because of their "wickedness".
19] Yet say ye, Why? doth not the son bear the iniquity of the father? When the son hath done that which is lawful and right, and hath kept all my statutes, and hath done them, he shall surely live.
 The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him.
 But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die.
 All his transgressions that he hath committed, they shall not be mentioned unto him: in his righteousness that he hath done he shall live.
 Have I any pleasure at all that the wicked should die? saith the Lord GOD: and not that he should return from his ways, and live?
