A lot of religious motivation is from schizoid personality defects, not from strong faith in God. [video lecture by Sapolsky (start at minutes 8:00 and onward. And in particular minute 1:15:16 [i.e. one hour and fifteen min.]) and https://www.youtube.com/watch?v=nEnklxGAmak] [See : Alfred Kroeber] Thus it is easy to see why the religious world seems so unhealthy. Clearly, this was noticed by Rav Israel Salanter who saw that the essence of Torah is Monotheism with good Midot [good character traits], not religions fanaticism. But that did not help after the first few generations of Musar. Eventually, it became another sort of religious fanaticism. [See: Geschwind Syndrome]
And this is the reason the religious people commonly refer to secular Jews as "crazy." כל הפוסל במומו פוסל." ''All who calls names calls with his own name." [ Gemara and brought in many Musar books.]
