The morality of an action depends on the motive from which we act. If I fling half a crown to a beggar with intention to break his head and he picks it up and buy victuals with it, the physical effect is good. But with respect to me the action is very wrong.
Sir, he [Bolingbroke] was a scoundrel and a coward: a scoundrel for charging a blunderbuss against religion and morality; a coward, because he had not resolution to fire it off himself, but left half a crown to a beggarly Scotsman to draw the trigger at his death.
