Satan wanted to be worshipped instead of God, so he rebelled and was kicked out of heaven, taking about 1/3 of the angels with him (now called demons). He still wants to be worshipped, that is his motivating ambition.
Isa 14:12-15 How you have fallen from heaven, O morning star, son of the dawn! You have been cast down to the earth, you who once laid low the nations! You said in your heart, “I will ascend to heaven; I will raise my throne above the stars of God; I will sit enthroned on the mount of assembly, on the utmost heights of the sacred mountain. I will ascend above the tops of the clouds; I will make myself like the Most High.” But you are brought down to the grave, to the depths of the pit.
Ezek 28:17 Your heart became proud on account of your beauty, and you corrupted your wisdom because of your splendor. So I threw you to the earth; I made a spectacle of you before kings.
1 Cor 10:20 No, but the sacrifices of pagans are offered to demons, not to God, and I do not want you to be participants with demons.
Matt 4:9 “All this I will give you,” he said, “if you will bow down and worship me.”
