Charles Dickens - Thus, to do ..

Thus, to do a great right, you may do a little wrong; and you may take any measure which the end to be attained, will justify; the amount of the right, or the amount of the wrong, or indeed the distinction between the two, being left entirely to the philosopher concerned, to be settled and determined by his clear, comprehensive, and impartial view of his own particular case. Ref. Dickens, Oliver Twist, chapter 12.
