Abbadon is an enigma. At times, he is an angel of judgment, not of satan but of God, destroying at God's bidding. Both Heaven and Hell claim him as an ally, other times as an enemy. It is clear that he is the angel who will command the monstrous horde from the Abyss that will rampage over the earth in the tribulation period as Judgment approaches. What is not clear is whose orders he will be following at what time.
