“Any humane and reasonable person must conclude that if the ends, however desireable, are uncertain and the means are horrible and certain, these means must not be employed.”

Helping one's fellow man in need, by reaching into one's own pockets, is a laudable and praiseworthy goal. Doing the same through coercion and reaching into another's pockets has no redeeming features and is worthy of condemnation.

The History of Freedom in Christianity (1877)
Context: The idea that the ends of government justify the means employed, was worked into system by Machiavelli. He was an acute politician, sincerely anxious that the obstacles to the intelligent government of Italy should be swept away. It appeared to him that the most vexatious obstacle to intellect is conscience, and that the vigorous use of statecraft necessary for the success of difficult schemes would never be made if governments allowed themselves to be hampered by the precepts of the copy-book.
His audacious doctrine was avowed in the succeeding age, by men whose personal character otherwise stood high. They saw that in critical times good men have seldom strength for their goodness, and yield to those who have grasped the meaning of the maxim that you cannot make an omelette if you are afraid to break the eggs. They saw that public morality differs from private, because no government can turn the other cheek, or can admit that mercy is better than justice. And they could not define the difference, or draw the limits of exception; or tell what other standard for a nation’s acts there is than the judgment which heaven pronounces in this world by success.

Judicial opinions
Context: It must never be forgotten, however, that the Bill of Rights was the child of the Enlightenment. Back of the guarantee of free speech lay faith in the power of an appeal to reason by all the peaceful means for gaining access to the mind. It was in order to avert force and explosions due to restrictions upon rational modes of communication that the guarantee of free speech was given a generous scope. But utterance in a context of violence can lose its significance as an appeal to reason and become part of an instrument of force. Such utterance was not meant to be sheltered by the Constitution.
