According to Christianity, Satan is the epitome and embodiment of all evil things, described as "the father of all lies" in the Catholic Church's Catechism . It is his works that tempt humans into doing bad deeds. If something evil occurs, we can be assured that Satan had something to do with it.

According to Catholicism, Satan only exists because God allows him to. This raises some serious issues about how righteous God can be if he allows evil to exist, but I digress. Satan, as the story goes, began as the angel Lucifer, who outrightly rejected God and rebelled against him. God cast Lucifer and those who followed him into Hell, a place of eternal torture and despair, where God was not present.

Now the question, we are never told why Satan rebelled against God. We're never given his side of the story. Were Satan's reasons for rejecting God and attempting to overthrow him legitimate?

Still wonderin till DiS day.. BTW I wonder why God don't want to kill him or better still forgive him so everybody could just stay in peace

He was jealous of God as if God is not jealous to. Rubbish!

The reason can not be legitimate because no matter how cruel you boss is, insubordination is an unforgivable sin, (God is not cruel though).

His sins were pride and jealousy, he want to usurp God because of men. Men live in three dimensions- Spirit, Soul and Body while Satan existed in Spirit then. All angels covet human body, Angels had sex with humans Gen.6v4. The jealousy that he had for what God gave men, made him rebelled against God.

Why God has not killed him, God is unquestionable.

theEYe21:
He was jealous of God as if God is not jealous to. Rubbish!

God is jealous but not a destructive jealousy. Exodus 20:5, 34:14 etc. It is in his word. Don't forget if you are not jealous, you're not in love. He is jealous because He loves us.

Fornication I guess
