This is why some Gnostics held Samael to be Ialdabaoth, while others him to be Lucifer against Ialdabaoth. Why YHWH is seen as the demiurge as some, Satan by others, or the highest Father by some Christians. No one can actually tell who is who for certain.
I think theres 2 demiurgic powers at work, neither really holding our best interest at mind, and that is Life vs. Death.
People confuse the two in that Life is uses the forces of death to increase life, and Death uses the forces of life to increase death. Its like a game of Go.
