Lord Coleridge Regina v. Dudley and Stephens
14 Q.B.D. 273 (1884)

"Though law and morality are not the same, and many things may be immoral which are not necessarily illegal, yet the absolute divorce of law from morality would be of fatal consequence...

"We are often compelled to set up standards we cannot reach ourselves, and to lay down rules which we could not ourselves satisfy. But a man has no right to declare temptation to be an excuse, though he might himself have yielded to it, nor allow compassion for the criminal to change or weaken in any manner the legal definition of the crime."
