The Musar movement had a good point. That is without Musar people have no idea of what Torah is about, --or worse than that, they substitute their own half baked ideas for the real thing. Musar has the advantage that it is legitimate Torah written by rishonim or by the sages of the achronim period. [I mean to say that when people came up with pseudo Torah, [fake Torah that seems like the real thing but to a trained eye it i clear that it is fake] that is when the Gra signed the letter of excommunication.]

On the other hand, even with Musat it is easy to get off track.

And even to learn Musar in the context of a regular Litvak yeshiva does not see to offer any guarantees.

No matter what one does, it is hard to come to straight forward Fear of God and Good Character Traits [midot tovot].

You would not think that Rav Nahman of Breslov would be one person able to solve this problem, but I found his advice very helpful. [And I did enough research to realize that the letter of excommunication does not apply to him. You can see that yourself if you find the actual language of the five excommunications that were published in Villna.] It was Rav Nahman warning that there is such a think as Torah scholars that are demons that gave me enough insight to realize the danger. That is even if I am not able to come to fear of God as well as I would like, at least I know who to avoid. Torah scholars that are demons--of which there are way too many nowadays.
