Short story “Benjamin Franklin” by Nathaniel Hawthorne (excerpt quoted below):
"Because," answered his father, "in building your wharf with stolen materials, you have committed a moral wrong. There is no more terrible mistake, than to violate what is eternally right, for the sake of a seeming expediency. Those who act upon such a principle, do the utmost in their power to destroy all that is good in the world."
"Heaven forbid!" said Benjamin.
"No act," continued Mr. Franklin, "can possibly be for the benefit of the public generally, which involves injustice to any individual. It would be easy to prove this by examples. But, indeed, can we suppose that our all-wise and just Creator would have so ordered the affairs of the world, that a wrong act should be the true method of attaining a right end? It is impious to think so! And I do verily believe, Benjamin, that almost all the public and private misery of mankind arises from a neglect of this great truth—that evil can produce only evil—that good ends must be wrought out by good means."
"I will never forget it again," said Benjamin, bowing his head.
"Remember," concluded his father, "that, whenever we vary from the highest rule of right, just so far we do an injury to the world. It may seem otherwise for the moment; but, both in Time and in Eternity, it will be found so."
