Sin is a curious predator.  The stocking of its prey is sufficient pleasure.  It doesn’t kill to eat.  It doesn’t destroy to retain its property.  And it really doesn’t care whether the sinner is pleased with its work or not.  I doubt that sin is even purely selfish.  The only thing sin has in mind is to destroy purity.  And if you could ask sin why, it wouldn’t have the slightest clue of an answer.

What should be done with an enemy like that?
