It is helpful that Rav Nahman of Breslov was aware of the problem of Torah scholars that are demons-which is admittedly a problem, [Le.M. I:12, I:28.] and yet was able to see the importance of the Oral and Written Law.

Abuse does not cancel use. Abusus non tollit usum.

In fact in the very first of the 13 stories of Rav Nahman  is an instructive lesson.  The second to the King, was on a search for the kidnapped daughter of the king.  When he got to giants in a desert that told him to turn back. But he was stubborn and pressed on. You can say this is similar.
