Angels were wild, vicious things.
Holy books proclaimed them to be humanity's loving protectors in the name of our Father, but the reality couldn't be further. They were like animals, cruel and predatory. Angels were strong, could easily break human bones like twigs. They could fly high and attack from above, or they could simply ambush from behind soundlessly.
They also had incredibly lustrous feathers, highly sought after for cosmetic reasons.
That was why they were hunted, human hunting parties growing very rich very fast if they could part wing and angel.
Dogs were not sufficient when tracking the elusive angels, and so humanity had turned to demons. Demons made excellent angel hunters, as they were natural adversaries, and were merciless when they caught their prey. Unfortunately they were also careless and a badly behaved Demon could easily damage the feathers that were the point of every hunt.
Little did anyone realise, that they themselves had made the Angels cruel, a measure of protection against the humans they had once watched over so carefully. That angels once were those kind and loving protectors. That humans had revered them as they walked the Earth, had spread their messages of joy.
That angels were wild and cruel because they had to be, to survive.
