Perhaps the most visible of the sins, gluttony is simply disgusting in appearance. To let one's body fall to the wayside because of want of some particular food, drink, or drug. In reality, gluttony is a more specific version of greed, though the effects are truly disturbing. People look at gluttons on the street and immediately recognize them. A glutton is one of the least respected people because of their appearance. Some gluttons simply have destroyed their mental capacity through excesses of drugs. Such a thing is a waste of creation, not worthy of the life they have been given. If they believe that their body is so horrific in the first place that they let it fall to decadence, then why not try to improve it instead? There is always room for improvement. It might not be easier, but it's much more rewarding.
