אִֽישׁ־בַּ֭עַר לֹ֣א יֵדָ֑ע וּ֝כְסִ֗יל לֹא־יָבִ֥ין אֶת־זֹֽאת׃
우준한 자는 알지 못하며 무지한 자도 이를 깨닫지 못하나이다
Sha'arei Teshuvah
And there are times when the merit of someone who is liable for excision lasts him two or three generations. And the delay in the death of evildoers is to pay their reward in this world, and so to destroy them in the world to come. For it is stated (Deuteronomy 7:10) “But who instantly repays with destruction those who hate Him - never slow with those who hate Him, but repaying them instantly.” And the thing is explained in the words of King David, peace be upon him (Psalms 92:7-8), “A brutish man cannot know, a fool cannot understand this: Though the wicked sprout like grass, though all evildoers blossom, it is only that they may be destroyed forever.” And likewise did Asaf, peace be upon him, say (Psalms 73:3-17), “For I envied the wanton; I saw the wicked at ease. Death has no pangs for them, etc. Until I entered God’s sanctuary and reflected on their fate.” Its explanation is that vengeance upon the evildoers is at their end, as it is stated (Proverbs 24:20), “For there is no future for the evil man; the lamp of the wicked goes out.”

Our Sages said further : "He who loses his temper, even the Divine Presence, is unimportant in His eyes (Nedarim 22b), as it is written "The wicked in the pride of his countenance (saith) 'He will not require', All his thoughts are 'There is no God' " (Ps. 10:4). And it (anger) also causes him to forget his studies of Torah and increases his folly as it is said : "For anger resteth in the bosom of fools" (Eccl. 7:9) and "A fool will not understand" (Ps. 92:7), and, "But a fool unfoldeth folly" (Prov. 13:16). You may be sure that his sins are more plentiful than his merits, as it is said : "An angry man stirreth up strife" (Ibid. 29:22) and his punishment is very great as it is said : "A man of great wrath shall suffer punishment" (Ibid. 19:19).
