Do you want to tie yourself up in knots? God knows all. He is omniscient. Then why are there incidents in scripture where it seems that God changed His mind? Jonah 3: 9-10, Genesis 6: 6-7, Jerimiah 18:8
He doesn't change His mind when He knew He was going to do that in the end. He just allowed it to take its course. Sometimes God wants us to learn heuristically. Anyway, to question God is useless. You won't know the answer until you see Him.
