Notwithstanding the magisterial from shame to sin which covers the development of the idea of Sin in Roman contexts I want to propose the following thesis vis-a-vis the nature of Sin.
That is to say that Sin i.e. the notion of the Sin makes sense only in relation to vita comunalis. I am borrowing H. Arendts monad of vita here although if my memory is accurate she is not the sole porprietor of this goad.
One counterargument could be the case of Abraham preparing to offer his son to God, as covered by Kierkegaard, which could be interpreted as Sin outside of active communal life.
