I'm an atheist, but I don't understand why Lucifer is considered bad. Because he didn't want to live on his knees, because he wanted to be free to make his own choices? Lucifer seems like a being who values free will, and I would rather spend my time with him than some god who expects me to bow before him.
I'm the same way. Even though I'm an atheist, objectively speaking, I have an easier time trusting the devil (Satan) than god (Yahweh). If you read the Old Testament closely, you can tell that Yahweh is egotistical and manipulative. He dangles hope and healing just out of people's reach, and only gives it when people are just about to give up. Like in the book of Exodus, when it took him 400 years to bring Jews out of Egypt. Also, in the book of Lamentations, he let his own temple get destroyed by the Babylonians, after the Israelites spent decades building it for him. Basically, he does to his believers what MHP's do to us: all platitudes and promises, and no actual results.
Satan, on the other hand, never actively DID anything bad to people. He just sits in front of a lake of fire where sinners allegedly go. Maybe the bad part is tempting people to sin, like an unethical salesman scamming customers. But that's it, really. You still have a choice to say no. And when you actually go to to hell, how are the flames supposed to hurt, when you don't have your physical body? Souls don't have neurons and pain receptors. I actually like the depiction of hell in Dante's "Inferno". Unlike the Christian hell, where everyone, from scammers to rapists, go the same lake of fire, Dante's "Inferno" has different parts of hell, depending on the severity of sin.
