Lucifer was made the brightest of the angels, the most powerful being outside of God Himself. Lucifer is sometimes recognized as the greatest of the cherubim (because the Cherubim defend the throne of God). He was the archangel, the head of the heavenly host. As with all angels, Lucifer had a specific purpose when he was created. He was HaSatan, in Hebrew, or the Adversary. This originally meant that Satan was in essence, the prosecutor of Heaven. However, out of pride, Lucifer defied God, proclaimed Himself to be better and tried for the Throne. He was cast out of Heaven. He has taken the name Satan, his title, to be interchangeable with his name, "The Bringer of Light."
He is a dark and loathsome creature now, who attacks the CHurch and mankind, hoping to take us with him into the Lake of Fire. I have no doubt that Satan now realizes he will lose, and with all evil maniacal beings, he has changed his plan. At first it was to win, and now it is to make God suffer as much as he can. Scripture tells us that God wills that none of us would perish, but we defy God. Behind this is Satan, he saw that God loved us, and through that love inflicts pain. He is not to be pitied, admired, or liked, nor is he to be hated. He is loathsome and deserves nothing but our refusal to serve him. We serve the Most High God, and Satan is the Enemy. Satan rules over the demons, and claims this world as his own. Here alone Satan has a legitimate argument. Because man refuses to acknowledge God, and have allowed Satan dominion over the world that was given to us, Satan can claim that we have given him dominion, and this is the very argument he makes before the Throne. I'm even sure that this is why God will give him his season.
