Hel. 13:29, evil is not what we ARE, but what we choose to become. Creation is perfect because it uses its agency to follow God. Until the fall the same could say the same about humanity. This just underscores the importance agency plays in the creation narratives.

Moses 2:2, I really like what you have to say about Darkness here, compared with what the Genesis text has to say. I’d also like to connect with verse with the Prologue of John’s Gospel. In John 1:1-5, I think John is saying something similar to what you are saying, that darkness is parasidic. Darkness cannot stand alone, it must have light in order to have life. Darkness feeds on (ie. drains) light in order to gain power. Although, at the same time, the darkness will never understand the light. Much more to say about that, but for now that should suffice.
