He thus creates both Good, and Evil, and existence is all the richer for it...and trying to skeeve the existence of evil off onto “Satan”, Adam, Eve, the Nephilim, you, me, whoever! just does a disservice to the true majesty of God’s creation.

I suppose I need clarification on "richer".

From the monistic lens, God doesn’t create duality as a cosmic principle. What we experience as duality... struggle, failure, conflict... is really misalignment with the source. God reaches into that misalignment and recenters it on Himself, transforming the struggle into growth, the failure into humility, and the suffering into compassion. Richness exists in that restoration, not in the fracture itself. Otherwise, what would be the motivation to change these things?

God doesn't need to punish or balance these things, it is a condition to be redeemed.

And yes, I share that instinct. Evil isn’t a separate being or substance to pin blame on. From the Orthodox perspective, our condition is more like a sickness... we need a physician. We need healing, and God is the one who restores what is fractured.

Heck, I'd almost go as far to say a satan is not real but a hallucination of our misalignment with reality. Jesus consistently exposes the powerlessness of Satan. Jesus in the desert, focuses on obedience and relational alignment, not on combating the adversary. Exorcisms - The “demons” are expelled, showing that what appears as opposition has no independent existence outside the relational context... Jesus often frames him metaphorically...

The duality we see... good versus evil... that’s really just a story we tell ourselves. It’s a projection, a way of trying to explain what’s really happening when our will is out of alignment.
