I just want point out that this is untrue it may have been awhile since I have read the bible, but, I do recall that the term scapegoat comes from a story in the scripture where a chief had placed the sins of the people upon a goat. A goat has no conscious thought according to the bible. It doesn't define the difference between willing or not, the party is a scapegoat either way. The thing that really should be looked at is the major contradictory in Jesus' self sacrifice; The bible says that life is precious and that it should not be made a sordid boon, but, Jesus goes right up and forfeits it. Another huge contradiction is Jesus summits to his fate because god willed it, but, right in the beginning in the book of genesis God created man in his image and free will to make their own decisions so when pontius sentenced him how was it gods will? When the book that is suppose to define moral relativity has a bunch of moral relativity in it, Who is defining it Man or God?
I'm agnostic by the way.
