Desire to avenge and vengeance.
To have thoughts of revenge and execute them means to be struck with a violent – but temporary – fever. But to have thoughts of revenge without the strength of courage to execute them means to endure chronic suffering, a poisoning of body and soul. A morality that notes only the intentions assesses both cases equally; usually the first case is assessed as worse (because of the consequences that the act of revenge may produce). Both evaluations are short-sighted.
Reveling in revenge.
Crude men who feel themselves insulted tend to assess the degree of insult as high as possible, and talk about the offense in greatly exaggerated language, only so they can revel to their heart's content in the aroused feelings of hatred and revenge.
