Someone help me understand something

Correct my understanding. Only a being imbued with Pleroma can truly "create", ie bring about another being of Pleroma. The Demiurge cannot "create" he can only construct. The Demiurge constructed the universe, constructed Eden, and constructed Adam and later Eve. As the Demiurge constructed Adam and Eve, they could not have been imbued with Pleroma. Sophia via the Serpent later imbued Adam and Eve with Pleroma, causing the fall.

So how is the Demiurge the bad guy? He never trapped Pleroma inside his construct, Sophia did that. In fact he did everything he could to STOP it from happening. He just wanted his constructs to propagate inside his constructed universe. A whole society of Archons effectively. Multiple times the Demiurge attempted to purge all Pleroma from his universe, but outside influence conspired against him to keep imbued humans inside of his construct. It's like if I was playing with legos and someone suddenly trapped a soul inside my lego guy. I didn't do that, but now I'm blamed for creating a prison planet, when all I wanted to do was play with my legos in peace. Stop putting logos into my legos!!
