It is a misconception that the Christians even believe that the devil looked like one , with horns & hideous looking:
Satan; Created in Power and Beauty
In Ezekiel 28:12-18 you will find God describing him: “Thus says the Lord GOD, You had the seal of perfection, Full of wisdom and perfect in beauty. You were in Eden, the garden of God; Every precious stone was your covering: The ruby, the topaz, and the diamond; The beryl, the onyx, and the jasper; The lapis lazuli, the turquoise, and the emerald; And the gold, the workmanship of your settings and sockets, was in you. On the day that you were created they were prepared. You were the anointed cherub who covers, and I placed you there. You were on the holy mountain of God; You walked in the midst of the stones of fire. You were blameless in your ways from the day you were created. Until unrighteousness was found in you.”
So Satan was created a cherub and he originally was “the anointed cherub that covered” the very throne of God. He was perfect and “blameless”. Reading God’s description in Ezekiel, you see all the precious stones that have ever been created are a covering of his: gold, emeralds, jasper, and so on. He was “full of wisdom and beauty” but his pride lifted up his self-worth and he became “unrighteousness” before God.
