That makes keeping the Law of Moses very hard because people tend to believe those that play the role as being authentic. So innocent people are led to sin by those that claim to lead them to virtue.
The first time I notice this problem mentioned was in the book of Reb Nachman from Breslov Vol. I ch. 12 even though he had mentioned something of that nature in ch 8., but I had glossed over it, and paid no attention. But chapter 12 made it difficult to ignore the issue. There he brings up this idea of Torah scholars that hate people that fear God simply and plainly.
It sounds kind of harsh in the ears of the religious world because the religious world likes to consider itself as above everyone else in virtue and intellect and all good qualities. It is hard to face the dissolving of that illusion.
This would not be an issue if the people that were held up as being Torah scholars were in fact so. But the true Torah scholars tend to hide in the corners, while the Torah scholar demons take the public stage.
The way you see this in the Talmud is that in one place in the Talmud troubles that come into the world are blamed on pseudo Torah scholars. That is in the end of tractate Shabat. [For some reason however Reb Nachman did not quote that Gemara.]
One approach to take to avoid this problem is to learn Torah either at home or in some place that is careful to stick to straight Torah like regular Litvak yeshivas in NY and Bnei Brak. But there are no simple answers. I think Reb Israel Salanter came close to some kind of answer in his idea of the Musar Movement [not that he use that term]. That is the emphasis on learning books on the simple and plain Ethics of Torah. In itself that is a great idea but as is obvious it can easily be derailed.
The oddest thing about all this is there is absolutely no mystery who the demonic Torah scholars are. Everyone knows. But no one wants to say anything because they are afraid of how it will reflect on themselves.
The best suggestion to deal with this problem is more or less simple and straightforward but lack of interest makes it impossible.
If you do take this suggestion to learn at home, I think the best idea is to simply go through the Avi Ezri of Rav Shach along with the books of the Gra. That pretty much covers the major principles of the Oral and Written Law
