Regarding morality that is “inherent in man”

I looked at the questions on the site but did not find a clear conclusion. In the end, I am trying to ask whether it is possible, or perhaps even probable, that we do not hit the morals that God intended, at least in certain parts. As stated, in your opinion there is a clear separation between morality and religious commandments (therefore there are conflicts that need to be resolved). But since our way of knowing what morality God intended is simply a direct result of education and independent research as we grow older, then we have no way to really know if we were right in everything, since morality cannot be learned from the Torah, so where can we learn it? "The eyes of reason" seems to me to be a very subjective term. You accept belief in tradition and religious commandments from considerations of reasonableness in the end (it is unlikely that a tradition with such a broad front was invented by man, etc.), whereas morality cannot be accepted from considerations of reasonableness.

It is always possible that we are wrong. So what? And is it impossible to make a mistake in Halacha? Is there a realm in the universe where we do not use our intellect and therefore can make a mistake? What does all of this have to do with my theses?
