Since Medieval times the following punishments have been assigned to the 7 deadly sins.
- Pride - You will be broken on the wheel
- Envy - Placed in freezing water
- Gluttony - Force fed rats, toads and snakes
- Lust - Covered in fire and brimstone
- Wrath - Live dismemberment
- Greed - Boiled in oil
- Sloth - Thrown into a snake pit
The list of the 7 sins came first from Pope Gregory I in 590 AD.
Dante then wrote his Purgatorio & Inferno with descriptions given as to the punishments given for the sins. These were sometimes conflicted between the two books, for example in Purgatorio the punishment for lust was to be walk in flames, however in Inferno the souls of those that had committed the sin of lust were blown upon the winds.
Dante also wrote that anyone that committed any of the deadly sins would never be able to look upon the face of God.
Various Theologians came up with the accepted punishments detailed above over the centuries following Pope Gregory I's official naming of the sins.
Numerous books on the 7 Deadly sins, as well as a number of websites, for example Sins, Virtues, and Tales explains these nicely.
