If God made man in his image that means Satan was too since he created Satan beautifully ?

The Bible pretty much lets on that Satan was a very good looking angel probably the best looking one in all of creation. But because of it Satan became too proud and decided that he should be worshiped

God created the Angel's first. Long before the universe was born. He gave them supernatural powers. But satan maybe he gave him too much spirit too much freewill too much independence.  Perhaps he "satan" thought he could do better. He became frustrated with his boss "god" that's how the civil war began in heaven satans allies vs the Angel's loyal to god. Who won? Is there any doubt when god has your back. 

Yes but we don't know if he retained his beauty after the fall.
