It is the deed that teaches, not the name we give it. Murder and capital punishment are not opposites that cancel one another, but similars that breed their kind. – George Bernard Shaw, Maxims for Revolutionists

In the whole vast dome of living nature there reigns an open violence, a kind of prescriptive fury which arms all the creatures to their common doom: as soon as you leave the inanimate kingdom you find the decree of violent death inscribed on the very frontiers of life. – Joseph De Maistre

And so, to the end of history, murder shall breed murder, always in the name of right and honor and peace, until the gods are tired of blood and create a race that can understand. – George Bernard Shaw, "Caesar and Cleopatra"
