It existed with Lucifer His corrupt thinking. By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
He’s an Archangel and our world isn’t his world. His reality isn’t our reality. He simply chose to not serve a Human in Jesus Christ. He couldn’t accept he would have to serve what he believed was below himself. That became the point of contention.
He though he should be God. You ever hear the saying, Be careful what you ask for, you just mught get it? So God cast him out of Heaven he tried to drag Michael down with him and he did drag many of the angels down. And he is the Prince of Darkness, he who rules hell. And who holds the keys to hell? Jesus Christ.
Problem is those angels Lucifer dragged down are demons. And the Free Will now became a choice of Good or Evil. Complicated by the reality that Lucifers attribute is to remain unknown and disbelieved. Thus he drags many Souls to his service,
There was no evil in the Garden till the serpent entered, thus there could not have been Sin. The serpent bought the temptation thus the sin. Adam and Eve made a choice through their Free Will. Which they did have. I just don’t believe they quite understood the magnitude of there Free Will and that it would come down to what it did.
Without a doubt Lucifer manipulated Free WIll. I agree he didn’t create it. But his effect on it has become basically a forced choice of Good or Evil? Of course you have the freedom of all that lies between those two ends. But those are the choices.
