The Doctrine of Total Depravity

The Doctrine of Total Depravity: A woman bakes a rich devil's food cake and covers it in frosting. At the end of the day, this is a rather rich cake, perhaps not as rich as it could be because the plan was not to make it that way, but it is still completely a cake and a rather rich one at that (i.e. humans are 100% sinful, messed up by the Fall, but God does not plan for everyone to be as sinful as possible).
