It's an allegory, (Moderator: quoted content removed)! It's typical of aggressive atheists, especially on here, to take the most literalistic, stupidest version of Christianity, and pretend that it is mainstream Christian belief.
For some it's an allegory - it's still a bad allegory - but for some it's literal truth. Regardless, it's still not a good message - fundamentally the lessons here are:
Those who acquire knowledge must be punished;
Those who are descendants of those who must be punished must also be punished for the transgressions of others;
God has no responsibility for the failures of his design.
Unless the concept of 'sin' is also 'allegorical', in which case the whole thing is just a second-rate Roald Dahl story waiting for it's third rate film adaptation.
As it is, I believe Spud (to whom I was replying) DOES think this is the literal case - I'll apologise if I'm misremembering that, but I was under the impression that was the case.
