A man who suffers an attack to his ego regarding his lack of power, may become wrathful and, while noticing that it makes him feel powerful, makes an unconscious pact with the devil to use wrath in order to feel powerful, casuing untold misery.
It's important to be cautious that we do not mistake wrath with power, because it is a trick that the devil uses to get people who envy the power of others to become more like him.
