Satan isn't anything to believe in but there are people running things whose God is Lucifer. Check out the Lucifierian Doctrine which Albert Pike wrote. He said it is given to 29th-33rd rank Masons in his book Morals and Dogma.

Lucifer was a true pioneer in the defense of basic moral rights and freedoms, questioning God’s omniscient authority over the world. He was at the forefront in the fight for the right to free thought, knowledge and will. Lucifer liberated a helpless species from a malevolent dictator and he is the one who suffered the consequences, with no praise or gratitude. By today’s standards we would consider him a saint, greater then Martin Luther King or Mother Teresa. But instead we condemn him, and follow God, undoing his ultimate sacrifice. Perhaps at the very least we owe him an apology?

It was when Lucifer first congratulated himself upon his angelic behavior that he became the tool of evil.

Of all the inhabitants of the inferno, none but Lucifer knows that hell is hell, and the secret function of purgatory is to make of heaven an effective reality.

Isaiah 14:12:
How you have fallen from heaven, morning star, son of the dawn! You have been cast down to the earth, you who once laid low the nations!
(NIV)
How have you fallen from heaven, O light-bringer and daystar, son of the morning! How you have been cut down to the ground, you who weakened and laid low the nations [O blasphemous, satanic king of Babylon!](AMP)
How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
(KJV)
