If God is Almighty and Holy in all his might, then why is it that He could'nt save lucifer from falling?

God is, by the biblical texts, Almighty, Holy, and is able to do anything. Then why is it that he couldn't save Lucifer from his fall? Even if God gave the angels their own will to praise God or rebel, it shouldn't mean that God should give up on those who fail to choose to praise him. God just gave up on Lucifer, punishing him into earth and casting him as the father of lies and of pure evil. (This is uming by some translations that Lucifer does exist). If God would have saved Lucifer with his infinite wisdom and ability, (uming he can since he can do anything) then 1/3 of the angels and ALL of humanity would NOT have fallen with him. God would've also been able to guide us all back to righteousness. However He only speaks of trying to save those who believe.. so he's giving up on nonbelievers? even if we're of the purest of heart thats able by human standards? so u save the darkest of hearted humans who repent but not those who are tainted humans with pure heart? If he truly loved us and is all knowing, then why didnt and still dont save lucifer? God in his all mightiness SHOULD be able to. and IF he did, things would not have to come to this.
