On the importance of Rule of Law and Procedural Justice rather than Distributive Justice

(RICH exits. All watch him; the others turn to mom, their faces alert)

ROPER: Arrest him.

ALICE: Yes!

MORE: For what?

ALICE: He's dangerous!

ROPER: For libel; he's a spy.

ALICE: He is! Arrest him!

MARGARET: Father, that man's bad.

MORE: There is no law against that.

ROPER: There is! 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 not what's right. And I'll stick to what's legal.

ROPER: Then you set man's law above God's!

MORE: No, far below; but let me draw your attention to a fact-I'm 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, oh, there I'm a forester. I doubt if there's a man alive who could follow me there, thank God . . .

(He says this last to himself)

ALICE: (Exasperated, pointing after RICH) While you talk, he's 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 benefit of law!

MORE: Yes. What would you do? Cut a great road through the law to get after the Devil?

ROPER: I'd cut down every law in England to do that!

MORE: (Roused and excited) Oh? (Advances on ROPER) And when the last law was down, and the Devil turned round on you-where would you hide, Roper, the laws all being flat? (He leaves him) 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-d'you really think you could stand upright in the winds that would blow then? (Quietly) Yes, I'd give the Devil benefit of law, for my own safety's sake.

If you have made up your mind beforehand on who is the Hero and who is the Villain, not only might you be wrong but if the facts (or your knowledge of them) changes, you most probably will not change your mind.

On the other hand, trusting to due process (alternatively: deontological principles or procedural justice), there is less chance of emotion, prejudice and bias affecting the outcome.
