The main source of ambiguity the straight and holy Path of the Gra, come from the fact that after  Yeshiva years,  things tend to go haywire  This led me to consider the vey important fact that according to the Rishonim, Torah is not Divine Decree Theory but rather that Divine decree is based on Reason.{And of course Reason was created by God. In fact in the Middle Ages there was no Divine Decree Theories even among Muslims and Christians. Things were not thought to be right or wrong because they were decreed by God but rather they were decreed by God because they were good.

Thus I noted that Torah is meant to bring to objective morality.
