Super interesting, but I think there is a critical misunderstanding of the story here. The tree of good and evil is often associated with "wisdom" but it should not be. Wisdom has nothing to do with the story in Genesis 3. First, the Bible often contrasts knowledge with wisdom. Second, the word "wisdom" never shows up within the whole of the story. The story rather seems to be talking about the actual knowledge of good and evil -- the receival of KNOWLEDGE of good and evil. The first thing that happens to Adam and Eve after eating the fruit is that they become aware of their surroundings within a framework of morality that they suddenly gain knowledge of, not anything related with wisdom.

This would give less credential to your point then of "God is both good and evil". I noticed how you switched to quoting the KJV rather than the ESV in that particular point and so I checked the ESV translation of Isaiah 45:7. The word "evil" in ESV is translated as calamity. It is clear from the context that "evil" here is not moral evil, but rather some form of punishment (towards the nation of Israel here). God is telling them that He is the one in control of whether they experience peace and joy or calamity and suffering. This further takes away the remaining credential to your point.
