The bible story has Satan as the created agent of God, fulfilling the purpose of God, doing the will of God.
Refer to Judaism.
Christians have serious difficulty accepting what the Book says in that regard, some are that silly they even claim not to have know about it.
God set Lucifer up knowing he would rebel, God set Adam up for temptation, knowing he would take the bait, God set Judas up for temptation, knowing he would take the bait.
NONE of which would be possible had God not allowed evil to be an official ingredient of his divine plan.
Satan is so important to God, that he even invites him to angel councils in heaven.
iF God tells Satan to do something, he follows it it to the letter without fail, something which christians cannot do..
That appears to be a case of inconvenient information. ''Now there was a day when the sons of God came to present themselves before the Lord, and Satan also came among them. 7 The Lord said to Satan, “From where do you come?” Then Satan answered the Lord and said, “From roaming about on the earth and walking around on it.” 8 The Lord said to Satan, “Have you considered My servant Job? For there is no one like him on the earth, a blameless and upright man, fearing God and turning away from evil.” - the book of Job.
