The Torah generally advocates for kindness and love toward all people, but it demands an unyielding and harsh response toward anyone who incites others to idol worship. While this severe approach might seem to contradict the broader obligation to love one's neighbor, an inciter threatens the very foundations of faith and society. Therefore, showing cruelty to such an individual is ultimately an act of profound mercy for the world, as it prevents widespread spiritual and social ruin [תורה תמימה].
The rejection of the inciter must begin internally. One perspective views this as a strict prohibition against even mental agreement. A person is forbidden to accept the inciter's ideas in their heart or to entertain the thought of investigating whether there might be some truth to the claims about the idol's power [אבן עזרא, ספורנו, העמק דבר, ביאור יש"ר]. Another approach frames this emotional distance as an exception to the rule of love. Because individuals are commanded to love their neighbors, one might mistakenly assume this duty extends to the inciter. The law specifically mandates that one must not love or seek any closeness with someone who attempts to lead others away from God [רש"י, גור אריה, מזרחי, חזקוני].
Moving from thought to action, the prohibition extends to how one responds to the inciter's words. Primarily, it is forbidden to accept the proposal to sin. In the unique case of an inciter, merely expressing verbal agreement to worship an idol is enough to incur the death penalty, even before any physical act of worship takes place [רמב"ן, רלב"ג, תורה תמימה]. Furthermore, one must remain deaf to the inciter's pleas for mercy. If the individual regrets the incitement and begs for forgiveness, it is forbidden to pardon them or to let go of the enmity toward them, standing in stark contrast to the general obligation to assist an enemy in distress [רש"י, שפתי חכמים, משכיל לדוד]. The only exception where one is permitted to listen to the inciter is when setting up a trap with hidden witnesses to ensure the person is brought to justice [רלב"ג, אדרת אליהו].
The strictness intensifies regarding the inciter's physical safety and legal standing. While the Torah normally commands individuals to save anyone in mortal danger, it is absolutely forbidden to protect an inciter [רש"י, גור אריה]. Commentators draw a distinction in the types of mercy that must be withheld. One must not feel pity for the individual out of personal affection or due to their potential usefulness to society [מלבי"ם, רש"ר הירש, ביאור יש"ר], nor can one spare them out of family loyalty [רמב"ן, רלב"ג]. In a legal sense, this translates to a prohibition against searching for or arguing any defense on their behalf in court [רש"י, מלבי"ם].
Consequently, the standard procedures for capital cases are entirely overturned for the inciter. Anyone possessing incriminating evidence is forbidden to conceal it. In regular trials, the court actively seeks to acquit the accused, and a judge who argued for a guilty verdict can change his mind to argue for innocence. However, an inciter is afforded no such protections; no arguments for merit are allowed, and anyone who argued for a conviction cannot retract their statement [רמב"ן, תורה תמימה, משכיל לדוד]. On a deeper, conceptual level, the inciter represents the evil inclination that tempts a person to sin. The most effective way to defeat this internal drive is not by hiding the temptation, but by exposing it and bringing it out into the open. Publicly revealing the temptation strips it of its power and ultimately subdues it [אור החיים].
