Simcha:
“halacha is not unethical, but one can be an Orthodox Jew and a Shomer Torah UMitzvos while still being unethical”
1. If the Torah and Mitzvos don’t say that something is unethical, then who are you to say that it is?
2. Do you accept upon yourself Torah UMitzvos? Are you willing to hurt people, commit crime, and fraud when the Torah requires you?
I think that there is an intuitive code, called “derech eretz” which is “kodma latorah”. However the Torah supersedes any d.e. considerations, and informs us on what true d.e. really is. I.E. “tikkun olam” is not a reform invention, it’s mentioned in mishna, but chazal used it sparingly.
