The funny thing is, "original sin" is a church doctrine that emerged many centuries after Christ, and it doesn't even stand up to scriptural scrutiny. The NT refers to "sin" coming into the world through "Adam", but what these religions don't tell you is that the early Christians viewed the Garden of Eden story as an allegory.
Jesus exonerated little children from inherited sin when he said that we had to be like them in order to enter the Kingdom of Heaven.
