If it should be my fortune to receive a benefit from one that afterwards betrays his country, I should still reckon myself obliged to him for such a requital as might stand with my public duty; I would not furnish him with arms, nor with money or credit, or levy or pay soldiers; but I should not stick to gratify him at my own expense with such curiosities as might please him one way without doing mischief another. I would not do any thing that might contribute to the support or advantage of his party. But what should I do now in the case of a benefactor, that should afterwards become not only mine and my country’s enemy, but the common enemy of mankind! I would here distinguish betwixt the wickedness of a man and the cruelty of a beast—betwixt a limited or a particular passion and a sanguinary rage that extends to the hazard and destruction of human society. In the former case I would quit scores, that I might have no more to do with him; but if he comes once to delight in blood, and to act outrages with greediness—to study and invent torments, and to take pleasure in them—the law of reasonable nature has discharged me of such a debt. But this is an impiety so rare that it might pass for a portent, and be reckoned among comets and monsters. Let us therefore restrain our discourse to such men as we detest without horror; such men as we see every day in courts, camps, and upon the seats of justice; to such wicked men I will return what I have received, without making any advantage of their unrighteousness.
