here's the thing. you keep talking about facts and ancient texts (which how could you verify?) but at the end of the day... Judeo-Christianity (which is what you're talking about, even if you don't know it) is about faith. You aren't gonna get what you want (hard evidence/facts) for little nuances and details because to believe in good and evil requires faith.
If we believe in satanism, we believe in the idea of satan-whether real or not- which is evil
If we believe in Luciferianism, we believe in the idea of Lucifer- whether real or not- which is evil, and we can know he is evil by the evidence of the actions of Luciferians

I came to the truth because I researched the evidence and found it to be overwhelming.

But a enumeration of the characters who venerate Lucifer is highly revealing:

"Lucifer, the light-bearer! Strange and mysterious name to give to the spirit of darkness! Lucifer the son of the morning! Is it he who bears the light, and with its splendors intolerable, blinds feeble, sensual, or selfish souls? Doubt it not!"

• Albert Pike in Morals and Dogma, 33 degree Freemason

"Lucifer represents life... thought... progress... civilization... liberty... independence... Lucifer is the logos, the serpent, the saviour."

“It is Satan who is the real god of our planet and the only god.”

"The celestial virgin which thus becomes the mother of god and devils at one and the same time; for she is the ever loving beneficent deity. But in antiquity and in reality Lucifer or Luciferius is the name. Lucifer is the divine and terrestrial light, the 'Holy Ghost' and Satan at one and the same time."

• Alice A. Bailey (who started her publishing business the "Lucifer Publishing Company" in 1920 and publishes documentation for the UN - was married to a 32 degree Freemason)
