How do you understand that sometimes it is the scholars who sin?

I often wondered how it was possible that sometimes it was the learned who committed sins that honest people who were not so learned in religion would not commit.
For example, many honest people in the Israel Defense Forces would not dare to support Bibi and his gang.
It turns out that no party (except his own) would dare to participate in this abomination.
And again, except for the religious and the ultra-Orthodox. Who, as a rule, study morality and the Bible and are supposed to see God as fearing, who repays the wicked with evil according to his wickedness.
How exactly do they sin in this?
 
It occurred to me that sometimes it is precisely the study of biblical morality and faith that can stumble in ways that someone less learned would not fall for.
I also found a nice tip.
In the Testimonies of the Jews, at the end of Chapter 4, it is written:
Beit Hillel says:
(Assumption A) A hollow person is (not much to expect)
(Assumption B) And the upper side brings the impurity (it is precisely the one who is supposedly morally supposed to be on top that sometimes actually brings the impurity and corrupts the people and their future)
 
How is my sermon?
