FNY: Yes, Rashi. Rashbam doesn’t start until the third Perek.
I believe we agree on this point. The “internal procedures” depend on a subjective understanding of the issues. The “Din” of “Yashar V’Tov” (a general moral) is determined in its practical application by Rava based on his understanding of the facts. The moral “Do good” may be objective, but its application certainly is not. This moves on to other examples as well, such as the recent call by one of the Chassidishe Rebbes to wear fake straimels due to the cost and current external pressures on not wearing fur hats. That may be “Yashar V’Tov”, but it is based on a subjective understanding of the facts with which others might disagree.
Now to move to a more difficult case, let’s take Mechias Amalek. The “Moral” of “Yashar V’Tov” would (Pashtus) say not to do so. Either you believe that “Morality” is overridden by Halacha (and you are not a Kofer), or you believe that Hashem is saying that is included in “Yashar V’Tov” and is moral. See the post that I linked to earlier in the thread for more on that.
