The more time Arad spent with Merida, the deeper his understanding of the demons' true nature got. The demons aren't evil, and they aren't barbaric; they are purely savage. As AO, he didn't create evil; what he created was freedom.
As Merida cried beneath him, he could clearly see her demonic soul, and from what he saw, he was even more surprised. Her soul was translucent, as clear as pure glass and burning with light. The only blemish on her was the traces of her human soul, staining the crystal-clear demon soul like a finger-mark.
It was a strange thing to see, but the demon soul was the one trying to cleanse the human soul, trying to revert it to its true nature. He grabbed her by the shoulders, sat up, and sat her on his lap as he held her tightly in a hug.
