Abbadona, not to be confused with Abaddon, is one of the fallen angels. He was a seraph before his fall, and was once the chosen companion of Abdiel. He is generally portrayed as an angel who was not entirely committed to the rebellion against God, and is often called the "penitant angel". Unfortunately for him, it is impossible for an angel to repent (at least according to Catholicism), for once an angel sins, he is "fixed eternally in evil", and he can think no more good thoughts. Abbadona is occasionally used as a lesson whose moral is that one must avoid misdeeds, for one may never get the chance to be forgiven.
