I'm a maltheist, and these are beliefs. This is my many thoughts on God & Samael.
God is evil, and a tyrant. I wouldn't never worship such a being. I would side with Samael. These are my reasons.
1). Samael is the one who planted the tree of good & evil. It was Samael's tree that Adam & Eve ate. He was the one controlling the serpent. Samael is the one that freed humanity from slavery. Samael gifted humanity with knowledge. The Angel Watchers gifted humanity with knowledge. Destroyed them with a flood. God really hates knowledge.
2). Samael is father or Cain, and Eve was consort. Making Samael our (the gentiles) father, and creator. We have his blood flowing in our veins. God didn't create you. You own nothing to God. It was Samael and Eve's union that humanity exist. Why do think God hated Cain so much? Manipulated him into killing Abel.
3). The Gentiles (we) have the Blood of The Fallen Angels in our veins. The Fallen Angels gave humanity knowledge. We won't have video games, and the modern comforts of living.
God wants to either destroy us or enslave. Humanity is damned (fated) to hell because we have the blood of fallen angels.
Technically God did absolutely nothing for us, but pain, suffering, and slavery.
