Musar su Esdra 9:2

One who does not perpetuate a dispute against those who stand on a path that is not good, and those that haul in iniquity, is surely punished for their transgressions in all their sins (of the actual sinners); and [also] transgresses a negative commandment - as it is stated (Leviticus 19:17), “and not bear sin because of him..” And it is stated (Hosea 10:9) “You have sinned more, O Israel, than in the days of Gibeah; there they stand; shall they not be overtaken [as] at Gibeah by a war upon scoundrels?” Its explanation is [that] if that generation (of Hosea) was standing there, they would not have overtaken those in Gibeah in war, to destroy the evil, as that generation had overcome [the evildoers of that time] in war. The understanding of “there they stand” is, if they stood there. And likewise “and leave his father” (Genesis 44:22) is, if he left. [This is] meaning to say, that their sin was of the type of sin of Gibeah. However [the earlier generation] was better than these, since they gathered and stood with their lives to destroy the evil. And it is stated (Judges 5:23), “‘Curse Meroz,’ said the angel of the Lord; ‘Bitterly curse its inhabitants, because they came not to the aid of the Lord, to the aid of the Lord among the warriors.” And it is stated (Deuteronomy 1:17), “do not fear in front of a man.” And anyone who is for God, may He be blessed, should give over his life for the sanctification of God, as it is stated (Exodus 32:26), “‘Whoever is for the Lord, come to me’; and all the Levites gathered to him.” And it is [also] stated (Numbers 25:7), “And Phinheas saw, etc. and he took a spear in his hand.” And it is an obligation on all that fear [God] - even if he is one that loves pureness of heart - to arouse zealotry when he sees that behold, the officers and the prefects are in trespass, as it is stated (Ezra 9:2), “and it was the hand of the officers and prefects who were in this trespass first.”

It is an obligation on everyone who reveres God and who is pure of heart to arouse jealousy in himself when he sees that "the power of the princes and the nobility is used to trespass." And our Sages, their memory is for a blessing, said : "Every wild outbreak that does not begin with the great ones, cannot be called an outbreak" (Genesis Rabbah 26:5). As it is said "Yea, the hand of princes and the rulers hath been first in this faithlessness" (Ezra 9:2).
