The scripture my friend is clear and evil is the correct word. If we say God isn't Sovereign and in complete control then to do a screw up like that, then we can't trust him that this won't happen again. God created his first two kids a man, then from the man the woman was conceived. They had the perfect play area then God allowed a poisonous snake into their play area. It is not my right as his creation to defy what he said just because I want to see him vulnerable like me. God is not evil but by creating Satan he created evil. He also foreknew this would happen. It's all according to his plan just like his Son manifesting into the flesh and covering our sin on the cross.
