Thanks very much for your thoughtful response. Great questions! Unfortunately, however, no clear answers.

The purpose of the series is not to elucidate my theological views, rather what the original text of Genesis means. So a better question would be, what is the author's view of God? The text merely refers to Elohim and Yahweh, without describing them or their attributes. The idea that God is all-powerful, all-knowing, all-good etc. is held by various Jewish and Christians, but were these later? I don't know. They are certainly theistic positions, i.e. implying a personal God. My own belief is that the ultimate source is impersonal. The Jewish mystical system the Kabbalah also believes that, and I strongly suspect that the text I'm discussing is a Kabbalistic document. But is that what the author means by 'Elohim'? It's not clear.

If you believe that God is all-powerful and all-knowing, then the only explanation for Eve's corruption is that 'she' had been given free will. But we have to remember that in these myths figures appearing as entities are often in reality cosmic principles/energies, which are personalised. This complicates any interpretation.

Your next question is unanswerable. We have to imagine what might have been the case if something which did happen hadn't happened. This 'humanity' would have been different, but I don't feel competent to speculate. It would be reasonable to say, however, that its evolution would have been slower. However, I don't think the word 'corrupted' is appropriate; that sounds like something more in line with the later Christian interpretation. I think, 'not in accordance with the original plan' would be better.

As to why God might not support the decision, probably best to wait until after the next article.
