What is the ruling on saying "I am a devil" if the intention behind it is "I am not good"?

A Muslim should not liken himself to Satan or say that he is Satan, even if he means that he is not good; because Satan is evil, an enemy to humanity, and banished from the mercy of Allah the Almighty. The Prophet, peace and blessings be upon him, said: "The evil example is not for us," and he also said: "Let none of you say, 'My soul has become wicked.'"
