If God is all-knowing why did He create Satan whom He knew would fall?
At the risk of sounding flippant, why not? For what reason or reasons should God have not created the devil even if he was going to fall? Just because God knows what will happen doesn't mean that the person (or angel) isn't free to make choices. Satan freely chose to rebel against God. God knew this would happen.
Nevertheless, let me offer some possible reasons why God would create Satan even though He knew he would fall and rebel.
It was necessary to have the fall so that God could then have a reason to die for our sins thereby demonstrating that God can and does provide the greatest act of love which is to lay down one's life for his friend (John 15:13).
The fall of Satan provides yet another method for God to be glorified in that God can use sin to prove that sin is "bad" and that God's Word about righteousness is true.
If God is to have creatures with free will, then the risk of rebellion is part of that freedom. Satan had that freedom and used it to rebel.
If God had not created Satan and instead another angel fell, then we'd be asking why God made that angel knowing he would fall.
God has reasons about which we know nothing.
I know my children will act badly at times, but knowing that does not mean mean that I shouldn't have kids. Part of the risk of freedom is that rebellion will be a reality.
Here is why this sort of apologetics is an evil lie by an evil ass licking liar.
If God knows what will hapen it means he made it happen and his own filthy lying Bible says that like in Rom.8:29-30 "For whom he did foreknow, he also did predestinate.... Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified."
What the Bible says about Free Will From the Skeptic's Annotated Bible
God determines who is going to heaven ...
"And as many as were ordained to eternal life believed." -- Acts 13:48
"For whom he did foreknow, he also did predestinate.... Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified." -- Romans 8:29-30
"Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began." -- 2 Timothy 1:9
"He hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will." -- Ephesians 1:4-5
"God hath from the beginning chosen you to salvation." -- 2 Thessalonians 2:13
and who is going to hell.
"God shall send them strong delusion, that they should believe a lie: That they all might be damned." -- 2 Thessalonians 2:11-12
"For there are certain men crept in unawares, who were before of old ordained to this condemnation." -- Jude 4
There's nothing you can do about it.
"For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth. .... For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy. For the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth. Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth. Thou wilt say then unto me, Why doth he yet find fault? For who hath resisted his will? Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus? Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour? What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction." -- Romans 9:11-22
The Fall of Satan may really have been the Fall of God. Satan never wrote a book saying how awesome he is nor does he have an army of apologists explaining away his cruelty, injustice, lies and contradictions with lies and dishonest theories.
When this dick sucker says, The fall of Satan provides yet another method for God to be glorified in that God can use sin to prove that sin is "bad" and that God's Word about righteousness is true. That's like having a bully friend of yours beat people up and you come running in for the rescue to look like a hero. Think about it, Satan gets sent to hell for not bowing to Adam a human being and now Satan gets to torture human beings for all eternity. Kinda looks to me like Satan and God are partners sort of like the Duke brothers in the movie Trading Places.
The dick sucker says, I know my children will act badly at times, but knowing that does not mean mean that I shouldn't have kids. Part of the risk of freedom is that rebellion will be a reality. The difference is that even this dick sucker apologist will probably be fair in punishing his disobedient children. They may get grounded, lose privileges or spanked but they will not be tortured for all eternity. The very God who this dick licker is defending tortures his kids for all eternity simply because they did not get with the program. God main reason for torturing people forever is that they don't love him and believe in him.
When it all becomes too absurd and even false logic fails the Christian apologists, they will say, "God works in mysterious ways."
