The Thieves and the Cock

Some thieves broke into a house and found nothing but a Cock, whom they stole, and got off as fast as they could. Upon arriving at home they prepared to kill the Cock, who thus pleaded for his life: "Pray spare me; I am very serviceable to men. I wake them up in the night to their work." "That is the very reason why we must the more kill you," they replied; "for when you wake your neighbors, you entirely put an end to our business."

The safeguards of virtue are hateful to those with evil intentions.
