LEV612 The law of love imposes a responsibility upon the Jew not only for his fellow's material well-being but also for his religious development. Should you observe your neighbor doing something wrong you are commanded to rebuke him. However, the utmost caution must be used not to cause him any shame or embarrassment: "… Thou shall not hate thy brother in the heart; thou shall surely rebuke thy neighbor and not incur any sin because of him"; i.e., do not incur any sin in the process of rebuking him. [Torat Kohanim on this verse].
