I think that God was wrong to "cast him out of heaven".  He disagrees with God.  So what?  What the hell is wrong with having one's own mind to think?  God created them all.  We all think.  Perhaps Lucifer is a little more complex than us, but still.  Isn't listening without question and own point of view basically allowing one's self to be a slave to someone?  God can't keep bullying everyone into getting on our knees and putting our heads down begging for assistance.  That's not right.  We were created with the ability to stand.  What's more, I think love should be unconditional.  Christianity teaches conditional love.  That's why humans are so fucked up.  When a child is loved unconditionally, they usually are alot better off as far as stability goes.  Lucifer and the rest of us deserve to be loved whether we stumble or whether we do just fine.  God IS wrong.
