Frédéric Bastiat said this quote

In the first place, it would efface from everybody’sconscience the distinction between justice and injustice.No society can exist unless the laws are respected to a cer-tain degree, but the safest way to make them respected isto make them respectable. When law and morality are incontradiction to each other, the citizen finds himself inthe cruel alternative of either losing his moral sense, or oflosing his respect for the law—two evils of equal magni-tude, between which it would be difficult to choose.
