They love seeing humans become unable to resist pleasure and succumb to evil, and they will use whatever means possible to lure humans onto the path of corruption - at times using their cunning, and at times using their demonic powers. If they whisper alluring words into a human's ears, whether they like it or not, it will induce a vision of the days of pleasure that could be. In spite of their wicked and oppressive appearance, once a human copulates with a demon, the sweet pleasure that exists solely to corrupt will guide the human further along the path of wickedness.
