If the law written on the heart can be repressed, then we cannot count on it to restrain us from doing wrong; that much is obvious. I have made the more paradoxical claim that repressing it hurls us into further wrong. Holding conscience down doesn’t deprive it of its force; it merely distorts and redirects that force. We are speaking of something less like the erosion of an earthen dike so that it fails to hold the water back, than like the compression of a powerful spring so that it buckles to the side.
Here is how it works. Guilt, guilty knowledge, and guilty feelings are not the same thing; men and women can have the knowledge without the feelings, and they can have the feelings without the fact. Even when suppressed, however, the knowledge of guilt always produces certain objective needs, which make their own demand for satisfaction irrespective of the state of the feelings. These needs include confession, atonement, reconciliation, and justification.
Now when guilt is acknowledged, the guilty deed can be repented so that these four needs can be genuinely satisfied. But when the guilty knowledge is suppressed, they can only be displaced. That is what generates the impulse to further wrong.
