The convoluted wording of legalisms grew up around the necessity to
hide from ourselves the violence we intend toward each other. Between
depriving a man of one hour from his life and depriving him of his
life there exists only a difference of degree. You have done violence
to him, consumed his energy. Elaborate euphemisms may conceal your
intent to kill, but behind any use of power over another the ultimate
assumption remains: "I feed on your energy."
