So, uhm, who or what is an angel predator?

“Did you ever notice how in the Bible, whenever God needed to punish someone, or make an example, or whenever God needed a killing, he sent an angel? Did you ever wonder what a creature like that must be like? A whole existence spent praising your God, but always with one wing dipped in blood. Would you ever really want to see an angel?” -Thomas Daggett, the Prophecy

And something out there preys on them?!
