“Halachah IS right and wrong.”
Yet I think we would all agree that there are plenty of things one could do that would be *technically* within the letter of the halacha but would nevertheless violate it in spirit. For example, it would be technically halachically permissible to leave a TV on before Shabbos in order to watch it after Shabbos starts (this is assuming one already owns a TV and watches it during the week; let’s not get into the TV discussion here.) But doing this would without question be wrong for a person who is Shomer Shabbos. I remember asking my fourth-grade teacher this question, and I’ll never forget her answer: “Well, you certainly could, but the question is whether or not you should.”
