Мусар к Кохелет 1:5

In the writings of the illustrious author of Toras Chayim (Chullin 86a) I have found a worthy explanation for the principle that the righteous suffer for the iniquities of the generation (Shabbos 33b). He writes that the attribute of judgment would really like to destroy the world whenever people fail to fulfill the will of the Master of the Universe, but the Holy One Blessed is He in His abundant mercy takes pity on His handiwork. This is, after all, the reason that He adjoined the attribute of mercy, that is, the name יהו"ה, to the attribute of judgment. However, the attribute of judgment continues to complain and demands that the Holy One Blessed is He should execute judgment upon the world. So what does the Holy One do? He grants the attribute of judgment a single righteous person who is weighed up against the entire rest of the world. In this way Hashem silences the attribute of judgment and saves the world. But just as soon as one righteous individual dies, another is born, in keeping with the verse, “The sun shines and the sun sets” (Koheles 1:5). This is the explanation of our teacher the illustrious Rabbi Chayim Shor in his commentary on the tractate Shabbos; see there.
