It seems to me that many people who have been brought up with strict rules of morality are sometimes the quickest to fall into the most base and abhorrent standing. This is because once they see that they have breached and fallen their high standards they no longer hold themselves to any standard whatsoever, they do not differentiate any further, and fall prey to the lowest standards. This was also what happened with the Golden Calf. Right after Israel received the Torah they fell all the way to idolatry.
Rabbi Nachman warns in Likutay Moharan, Torah 31, that when one suffers a fall in his state of devotion he should not bolster himself with erudition, but just with loyalty of his covenant with G-d.
In Torah 78, of Likutay Moharan vol II, Rabbi Nachman reveals that even the greatest tzadik will have times that he can not draw his life source through the holy Torah, at such times the tzadik will be "prostik" -- simple (this word insinuates even coarseness, friends refer to it as urban language "plastic"), his existence based on Derech Eretz which preceded the giving of the Torah. In this way the tzaddik draws life to all the people in the world who are unable to draw life from the Torah itself. Derech Eretz is the way of Na Nach Nachma Nachman MeUman, it is based on the absolute faith in G-d and His infinite mercy which is embedded in the world, as it compromises the living blueprint of the world - the Ten Sayings which are paralleled in the Ten Commandments and Ten Sefirot.
As a captive to pirates, on his return to Russia from Israel, Rabbi Nachman achieved the realization and know-how of how to serve G-d completely even if he would be sold into slavery.
Any person wherever and whatever predicament they might be in, can bind themselves to Rabbainu, Na Nach Nachma Nachman MeUman, and set a constructive course and life plan. It is not all or nothing, every little bit is eternal, and even in the finite, will be a building block which will B"H ultimately be helpful in reversing everything to the best.
Na Nach Nachma Nachman MeUman!
