So long as men desire to live together, no man may initiate the use of physical force against others. . . . When a man attempts to deal with me by force, I answer him by force. It is only as retaliation that force may be used and only against the man who starts its use. No, I do not share his evil or sink to his concept of morality: I merely grant him his choice, destruction, the only destruction he had the right to choose: his own.
