In the earliest versions, and still is in the Jewish faith, he is literally an agent of God. God tells him to test folks, and he does his job. The whole War in Heaven and the idea that he had fallen come much later.

The ones that teach what Jesus supposedly did do not substitute God’s love for self love. He was asked if the myriad Jewish laws were still in effect or if Jesus’ coming had nullifiedthem according to prophecy. Jesus basically says, “love God, love your neighbor, and love yourself. Do these 3 things, and you will never break any moral law. You don’t need a list of commandments to follow, because you won’t break them if you follow these three.”
