Halakhah su Ecclesiaste 11:10

Anger is also a very evil trait, and it should be avoided it at all costs. You should train yourself not to become angry even if you have good reason to be angry. And when it is necessary to impress your authority on your children and your household, you may pretend to be angry in order to admonish them, while retaining your composure inwardly. [The Talmud relates] "Eliyahu said to Rabbi Yehudah, the brother of Rav Salla, the Pious: "Do not become angry, and you will not sin," (do not become angry, because anger will induce you to sin), "Do not become intoxicated, and you will not sin."⁷Berachos 29b. Our Rabbis of blessed memory said furthermore,⁸Rambam, Hilchos Dei’os 2. "If anyone becomes angry it is considered as though he worships idols, and the torments of Gehinnom will be inflicted on him as it is written, "Therefore, remove anger from your heart and put away evil from your body."⁹Ecclesiastes 11:10. The word "evil" connotes Gehinnom as it is written: "Indeed, even the wicked for the day of evil."¹⁰Proverbs 16:4. The life of angry men is no life. Therefore, [our Sages] ordained that a man should distance himself from anger to the point that he can conduct himself with utter disregard even for things that evoke [justifiable] anger. This is the proper path [to follow] and it is the way of the righteous, [as stated in the Talmud]¹¹Yoma 23a. "They suffer insults but do not insult, they listen to abuse heaped on them but do not answer, they are motivated by love in whatever they do, and they rejoice [even when] suffering pain." Concerning them, the Biblical verse says: "But those who love Him are as the sun when it comes out in its might."¹²Judges 5:31.
