Pilate was manipulated by the Pharisees. Whether they were working under God’s guidance will depend n whether you think as a Jew or not.
Your view of God seems to be very low inasmuch as you seem to think humanity cannot do any good without Him. That is a very poor view of God’s handiwork in creation If humanity is the pinnacle of creation then God did a pretty bad job of it from your perspective.
Either that, or God deliberately made us inadequate, either way it don’t look good on God!!

If God did author Scripture why are there errors in it?
