"A mitzvah induces another mitzvah and an aveiroh induces another aveiroh, since the reward of a mitzvah is another mitzvah while the reward of an aveiroh is another aveiroh" (Ovos 4:2). It seems from the Mishnah that a person whose neshomoh has not been sullied by cheit and has remained pure as when it was initially created by the Creator, cannot possibly be so blind as to sin. How can such a person not see the truth?
