“So morailty is relative?”
I didn’t address this question in my preceding comment.
“Because in a case of a machlokes, for person A the same act is moral and for person b it is immoral.”
That can very well be the case. It would be immoral to break a minhag inappropriately. If someone’s psak is to do A while another person’s psak is not to do A, it would be moral for the first person to do it but immoral for the second person to do it.
“I’m not setting up a argument per se, it just seems funny.”
May I submit that you might find it funny because your idea of morality is influenced by non-Jewish ideas on the subject?
“Incidently there is a moral sense outside of halacha. Rashi says in many places that “mishpatim” are rules that we would come up with on our own like no stealing, no killing etc…
Though this doesnt disagree with your main point, which may not be incorrect”
Those examples are within halacha, not outside it (killing and stealing are halachic points – even if we could have figured them out on our own), so I’m not following your point on that.
