I'm not religious, but think about it.
God believes in keeping the population ignorant. He hates free will. He wants to enslave us to his ideology. He has committed genocide countless times in the bible, going against his commandment, proving God has lied and is not perfect. He wants you to blindly follow him like a dictator, and punishes you if you don't.
Satan believes in free will and the ability to choose. He promotes knowledge and science. He hasn't killed anyone. He doesn't do anything if you don't follow him.
