In the irresistible logic of guilt, one evil leads to another, one sin is developed out of another. There is nothing abrupt, nothing casual in the process. The road to sin is smooth, because an army of transgressions has passed over it. When such a development takes place, the community is filled with consternation. Men meet each other and say, "Have you heard what has happened? Mr. A. has turned out a defaulter. Mr. B. has been robbing his bank. How could he have done it?" Alas! he did it long ago, when he took the first step, when he diverged a very little way from the path of right. After that, every other step was easy, natural, and logical.
