Well, it gets complicated...
The story centers around a Roman slave's 2,000 year hunt for Satan's brother. He spends most of his time in seclusion, save for the action scenes, which is where I focus my writing.
The antagonist is a complex character and I really want to explore his nature in the text.
Showing everything from the protagonist's pov makes that impossible.
Trying to find a way to work in the point of view of a reluctantly fallen angel is difficult. Lucifer deceived his brother, who now wants nothing more than to return to grace and becomes rather violent upon learning he cannot do so.
The MC, obviously, does not know his history and has no sympathy for the devil, so to speak. He has nothing kind to say about our demonic antagonist, yet he has sympathetic qualities.
