The demons certainly cannot have any faith in the words of authorities. In fact, they are always disrespectful to authorities. They manufacture their own religious principles and disobey great personalities like Vyāsa, Nārada and even the Supreme Personality of Godhead, Kṛṣṇa. As soon as one disobeys authority, he immediately becomes very sinful and loses his good fortune. The King was so puffed up and impudent that he dared disrespect the great saintly personalities, and this brought him ruination.
