We must endow our man with the full complement of injustice; we must allow him to have secured a spotless reputation for virtue while committing the blackest crimes; he must be able to retrieve any mistake, to defend himself with convincing eloquence if his misdeeds are denounced, and, when force is required, to bear down all opposition by his courage and strength and by his command of friends and money.

Plato, The Republic (Glaucon describing a paragon of injustice)
