The Original Sin can be interpreted as a sign of human metaphysical evil; says James Chastek:
… at the highest point of physical creation, there must be some connecting link between the spiritual and material world. This means at some point making spiritual things that exist with an essential relation to matter.
What an awful idea! Such a being will be subject to chance, to things he is not ready for, to his own impenetrable ignorance, and to the collective burden of all the mistakes, errors and sins that arose before him!
This practically guarantees that the very thing that we put at the perfection of the physical world will be the ugliest thing in it! The whole cosmos will conclude to a monster!
Well, not necessarily, but point well taken.
