The sin of anger is the sin that kills. The prophet Moses was prone to fits of rage. The mythic warriors of Sparta meditated in order to banish the sin of anger before a battle. Italian writer Dante placed those that committed the sin of anger in the "Fourth Circle of Hell," tearing each other limb from limb for eternity. Those who study demonology claim the sin of anger is really the possession of the body by the demon Ammon. Today, neuroscientists believe they've found the emotion of anger in the "amygdala." So, is the sin of anger demonic or chemical?

In this intriguing series, HISTORY examines the impact of the seven deadly sins on mankind throughout the ages.

We learn how the concept originated 'as a way to keep a lustful fourth-century monk from sinning again 'and how they were pared down from eight to the seven we recognize today: gluttony, lust, greed, anger, sloth, envy, and pride. For the Catholic faithful they became a guide on the path to heaven. To repeat offenders, they promised damnation in Hell and very specific, very gruesome punishments. Gluttons, for instance, would be force-fed rats, toads and snakes.

The warnings couldn't be clearer: Succumb to any of the seven deadly sins and God's judgment will be severe.
