Criticism of the Doctrines of Original Sin and Atonement:
The doctrine of Original Sin (or Total Depravity or Total Inability) is central to Christianity. On top of this doctrine a whole bunch of other doctrines were developed. Without Original Sin, humans are free from eternal sin and there would be no need for Jesus to be crucified in order to save them, and the doctrine of Atonement becomes unnecessary. Thus, without Original Sin, the whole system of Christian beliefs would fall apart.
The net is full with websites and articles that expose the absurdity of Original Sin and Atonement. Titles 1-7 in this selection discuss Original Sin, and titles 8-14 discuss Atonement.
