Its possible, that Aron is referring to specific tribe of Israel ( and not all human) , as in future events it told they have a prophets among them for many years but yet they keep turning away from covenant

Not sure how do you see a US empire, who has killed millions across the world in the name of moral code ( democracy and freedom) and still continue while I do not see any moral person protesting against them ?

Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in God, the Last Day, the angels, the Book, and the prophets and gives wealth, in spite of love for it, to relatives, orphans, the needy, the traveler, those who ask [for help], and for freeing slaves; [and who] establishes prayer and gives zakah; [those who] fulfill their promise when they promise; and [those who] are patient in poverty and hardship and during battle. Those are the ones who have been true, and it is those who are the righteous (Quran: 2:177)
