In the council of heaven as found in Moses 4, the Father explains that Jehovah was the chosen one from the beginning. It’s at this point that Lucifer tries to change the rules of engagement for exaltation. Notice that he (Lucifer) offered no agency in either sense of the word. He offered 1) no freedom of choice and 2) no power to act righteously.
In fact, Lucifer only addressed one aspect of God’s plan, the law that states: no unclean thing can dwell in the presence of God. He overlooked in his haste to formulate a competing plan, the aspect of becoming like God versus simply being with God.
