The devil here (commission work)

This illustration illustrates if human nature is more savage and more evil than the devil I describe as a boy whispering his desires beyond the devil's desires I illustrate as a goat with the analogy of “parents: how much money should be spent on school? (It should be $ 20) Satan whispering a price of $ 30 and the boy is whispering a price to the devil, which is $ 50, that's the greedy human analogy than anything.
