What if Satan didn't rebel or fought against God ?

This is a prediction of things to come, not something that has already happened. What I am seeking is the biblical basis for the biography of Satan as it stands in todays Christian mythology.

Chiang_Mai_boy, Read Isiah 14:12-17 and Ezekiel 28:11-19. By the by, Christianity is not a mythology. It is the faith we have in our Lord and Savior Jesus the Christ.

Isiah 14:12-17 refers not to Satan but to the ruler of Babylon. Ezekiel 28:11-19 is addressed to the prince of Tyrus and there is no discussion of Satan included. I am still looking for some biblical biography of Satan and I am still coming up short. In Christianity there is the faith that arises from the Bible and there is another story that has developed which has no biblical foundation. The latter can be and should be classed as mythology. I am not using the term mythology in a dismissive manner. All religions and in fact all cultures have a founding mythology as their foundation.
