“Implacable hate, patient cunning, and a sleepless refinement of device to inflict the extremist anguish on an enemy, these things are evil; and, although venial in a slave, are not to be forgiven in a tyrant; although redeemed by much that ennobles his defeat in one subdued, are marked by all that dishonors his conquest in the victor.” – Percy Bysshe Shelley, “A Defence of Poetry”
