Albert Camus said this quote

So it came to this, that— against the grain, no doubt—the condemned man had to hope the apparatus was in good working order! This, I thought, was a flaw in the system; and, on the face of it, my view was sound enough. On the other hand, I had to admit it proved the efficiency of the system. It came to this; the man under sentence was obliged to collaborate mentally, it was in his interest that all should go off without a hitch.
