There is a widely held belief that when we sin, as everyone inevitably does, we corrupt ourselves in some fundamental and irredeemable way. The Torah strongly disagrees:
כִּי-יִהְיֶה רִיב בֵּין אֲנָשִׁים, וְנִגְּשׁוּ אֶל-הַמִּשְׁפָּט וּשְׁפָטוּם; וְהִצְדִּיקוּ, אֶת-הַצַּדִּיק, וְהִרְשִׁיעוּ, אֶת-הָרָשָׁע. וְהָיָה אִם-בִּן הַכּוֹת, הָרָשָׁע–וְהִפִּילוֹ הַשֹּׁפֵט וְהִכָּהוּ לְפָנָיו, כְּדֵי רִשְׁעָתוֹ בְּמִסְפָּר אַרְבָּעִים יַכֶּנּוּ, לֹא יֹסִיף: פֶּן-יֹסִיף לְהַכֹּתוֹ עַל-אֵלֶּה מַכָּה רַבָּה, וְנִקְלָה אָחִיךָ לְעֵינֶיךָ – If there is a dispute between men; they shall approach the court, and the judges will judge them, and acquit the innocent one and condemn the guilty one. If the guilty one has incurred lashes, the judge shall make him lean over and flog him in front of him, commensurate with his crime, in number. He shall beat him with forty lashes; he shall not exceed, lest he give him a much more severe flogging than these forty lashes, and your brother will be degraded before your eyes. (25:1-3)
Aside from the facts of the case the Torah describes, it is noteworthy that the very instant the crime is remediated, the Torah reclassifies the offender as “your brother” – רָשָׁע / אָחִיךָ.
From this, the Sifri derived the fundamental principle that we must rehabilitate offenders. Once a wrongdoer has made amends, he becomes your brother again. For example, he is permitted to be a witness like anyone else, and his testimony is no less credible. The stain on his character is temporary, not permanent. He is not an “ex-criminal” or “Baal Teshuva”; he is “your brother.”
R’ Jonathan Sacks teaches that Judaism believes in rehabilitation both spiritually and in civil law. Beyond the natural drive to protect the rights of those who have been wronged, the Torah also seeks to help wrongdoers rebuild and make amends.
When someone sins or stumbles, the Torah condemns the act, not the person. The moment a wrong has been made right, anyone can become “your brother,” once again.
Hate the sin, not the sinner.
