These origins do not indicate any sense of pure evil. Rather, they convey the idea of one god opposing another. The image of Satan as an evil spirit, tempting mankind astray, undoubtedly has its roots in the Garden of Eden story. Lucifer, another name for The Devil, does not mean anything evil by definition.
Lucifer means to bring or bear light.
It is thought that The Devil used to be good until he chose to rebell against God and was cast by God out of Heaven and to the earth where he is believed to roam. When he was good, before his fall, his name was Lucifer. There is an interesting thing that connects Lucifer to Jesus Christ. When you look up 'Lucifer' in most good dictionaries you will find that Lucifer is another name for the morning star. The morning star is the planet Venus when seen during the day.
