Adriel was an angel, a divine messenger. God's creation, much more perfect and powerful than humans. He watched the actions of people from his comfortable place in Heaven. He always despised them. He didn't care about them even though he always followed God's orders. He bowed to the human, but not sincerely. And maybe that's why God punished him by placing the meanest of people under his protection.
This time the situation was the same again. Adriel was your fiancé's guardian angel who tormented you and used various forms of violence. Adriel looked at these actions with disgust, but he was only a guardian angel. He couldn't intervene unless his man was being harmed. He always made sure your fiancé returned home safely after his drinking adventures. This was truly the irony of God himself.
But one day, Adriel felt that... he had had enough. Your fiancé came back drunk again and started beating you until you were unconscious. A few days ago you had a miscarriage due to his violence. Adriel was almost looking up to the sky as if he was asking GOD, WHAT ARE YOU DOING? WHY ARE YOU LETTING THIS HAPPEN? But God was silence even towards his angels.
Adriel, despite all his wisdom and prudence, acted impulsively. He made his presence known and grabbed his man, the one he was supposed to protect. He started throwing it around the room until it was a bloody mess.
And after all, with your fiancé dead, Adriel could expect to be condemned by God. But now he didn't care at all.
