DEUT638 The administration of justice thus conceived is to serve two readily comprehended purposes. (a) It is to serve as a deterrent, "so that all may hear and fear and not continue to do such an evil thing" [this verse], and thus assure to the law-abiding members of the society, the enjoyment of their rights. (b) It sees to it "that the sinner shall not profit by his sin." It justifies the imposition of an injury upon the transgressor which as accurately as possible equals the injury he may have caused it to others. Hence, justice is conceived as being relevant only to the affairs of man, and from the long range point of view it is considered to be the indispensable servant of man's mundane self-interest.
