בַּעְנָשׁ־לֵ֭ץ יֶחְכַּם־פֶּ֑תִי וּבְהַשְׂכִּ֥יל לְ֝חָכָ֗ם יִקַּח־דָּֽעַת׃
Quando o escarnecedor é castigado, o simples torna-se sábio; e, quando o sábio é instruído, recebe o conhecimento.
Rabbeinu Yonah
"and judge every person as meritorious": This is speaking about a person about whom we do not know if he is righteous or if he is evil; or if we know that he is a moderate person, sometimes doing evil and sometimes doing good. And if he does something that can make us judge him unfavorably and [also] judge him favorably in our understanding - or even if, (towards) according to what appears, it leans more towards the side of guilt - if he can judge him favorably from one aspect of the matter, he should say, "His intentions were good." But these words are not [applicable] to the completely righteous or the completely evil. As with the righteous person, even with an action that is completely evil and leans toward guilt in every aspect, we should judge him favorably and say, "'It was a mistake that came out from the hand of the ruler,' and behold he regretted and observed [it] and [already] requested forgiveness." And it is like the sages, may their memory be blessed, said (Berakhot 19a), "If you see a Torah scholar who sinned at night, do not ruminate about him during the day, lest he has repented. 'Lest' comes into your mind? But rather, I will say he certainly repented." The explanation of "'Lest' comes into your mind?" is that since he is a Torah scholar and up until now, no corrupt thing has come to his hand; he certainly repented right away. You behold [from here that] one should never judge the perfectly righteous person unfavorably. And about him there is no reason to say, "judge every person as meritorious." And he also did not speak about the completely evil person. Even if his actions are completely good and it is not evident to be concerned about him regarding an angle of iniquity, a person should judge him unfavorably and say, "He did it on the surface 'and his inside is not like his outside.'" And it is like it is stated (Proverbs 26:25), "Though he be fair-spoken do not trust him, for seven abominations are in his heart." And so [too] wrote Rambam, may his memory be blessed. And about this Shlomo stated in his wisdom (Proverbs 21:12), "The righteous one observes the house of the wicked man; he subverts the wicked to the bad." He meant to say, people think that because the righteous do not know how to do evil, [hence] they do not recognize they ways of the evil - as they do not understand those that do it. And the matter is not like this, as 'the righteous one observes the house of the wicked,' and knows and recognizes and monitors the evil of his ways more than other people who know [about it], but don't pay attention to it. "He subverts the wicked to the bad" - when the righteous person sees the action of the evildoers which appear to be in a good path, he subverts it and pushes it towards his judgment to say that he has done wrong - since he did not intend [to do] a commandment, but rather to place himself among those assumed to be good.
