For safety, Let Devil have Law's Benefit

—
Margaret: “Father, the man is bad.”
More: “There’s no law against that.”
Roper: “There is a law against it. God’s law.”
More: “Then God can arrest him.”
Roper: “Sophistication upon sophistication!”
More: “No. Sheer simplicity. The law, Roper, the law. I know what’s legal, but I don't always know what’s right. And I'm sticking with what’s legal.
Roper: “Then you set man’s law against God’s?”
More: “No. Far below. But let me draw your attention to a fact. I am not God. The currents and eddies of right and wrong, which you find such plain sailing, I can't navigate. I'm no voyager. But in the thickets of the law, there I am a forester. I doubt if there’s a man alive who could follow me there, thank God.”
Alice: “While you talk, he is gone.”
More: “And go he should, if he was the Devil himself, until he broke the law.”
Roper: “So now you'd give the Devil the benefit of law!”
More: “Yes. What would you do? Cut a great road through the law to get to the Devil?”
Roper: “I'd cut down every law in England to do that!”
More: “Oh? And when the last law was down, and the Devil turned round on you -- where would you hide, Roper, the laws all being flat. This country’s planted thick with laws from coast to coast -- man’s laws, not God’s -- and if you cut them down -- and you're just the man to do it -- do you really think you could stand upright in the winds that would blow then? Yes, I'd give the Devil benefit of the law, for my own safety’s sake.”
