@Rage Lonethorn - Basically, it's not so black and white that all angels are good and all demons are bad. Gabriel (in the movie Constantine) was basically trying to raise the devil's son to inspire men to greatness by facing great darkness... to him that was 'good'. He was serving his purpose and gaining souls for his side by inspiring them to overcome something considered dark and evil. Angels are typically viewed as good because their job is to win souls for Heaven but they can go about it in many different ways... Not all of them good in the typical sense. Angels go bad, demons can rise to goodness... it just takes the right inspiration. Also, Angels aren't just floating balls of good will in the form of people or mystical beings... they are soldiers, they are weapons, they kill. They're expected to mass murder cities on an order (Sodom and Gomorrah), innocents and sinners alike(death of all first born sons in egypt) and then the next day pat people on the heads and say, "Sorry about that, but orders are orders, lets get to saving your souls shall we?" An angel's concept of goodness is determined by their goals and by their orders.

If you're asking what would happen to an angel cast out, they become fallen and if they choose to go even darker after that they become demons.

@Stephan Heya! Nice to see you around... Maybe you'd like to throw in some ideas here?
