Free will rules. Apparently, even the angels had free will.
I’ve always found it interesting that the angels are described as “fallen” and “elect”.
I don't include Angels because they are entirely different than us.
I do believe Adam and Eve operated freely. However in a different dispensation the Pharaoh's heart was hardened by God so that the plagues would continue. In that case the Pharaoh couldn't have stopped the enslavement of the Jews even if he wanted to.
