The conception of Sin which is bound up with Christian ethics is one that does an extraordinary amount of harm, since it affords people an outlet for their sadism which they believe to be legitimate, and even noble. Take, for example, the question of the prevention of syphilis. It is known that, by precautions taken in advance, the danger of contracting this disease can be made negligible. Christians, however, object to the dissemination of knowledge of this fact, since they hold it good that sinners should be punished.
