Lucifer can be seen as the light bearer, cast out because he thinks man can prosper without needing God. Hence wanting to attach soul to technology rather than nature.. life-extension, need to control ppl. Not necessarily all bad.

One myth is that he is put in his place by St. Michael, the spiritual son of Jesus. Learns to love God. Satan can be seen as more of an adversary or deceiver. One who partakes in abominations.
