Michael, I know you have this theory and fixation about 'blame', which I, personally, do not see. 
There first has to be 'sin' or 'evil' or something that is 'blamed'. True, the myth story does have 'Adam' blaming his wife's cooking the fruit; and then 'Eve' 'blames' the wiley Serpent, who ultimately seems to get 'blamed' for it all. 'Blaming' others seems to be a way of trying to avoid one's own responsibility. 
The myth story does have 'blaming', but I don't see that as the point of the story.
