Halacha and morality

peace,
I am currently engaged in a lot of discussion about the relationship between halacha and morality. I read your article in Akademo (from many years ago) regarding Hebrew law, and Rabbi Yaakov Ariel's response, which mainly concerned the relationship between musar and halacha. He ostensibly presented a different system than yours. After reading many of your words about halacha and musar, I wondered how much he really disagrees with you or whether he just wants to emphasize some aspects that you did not address. After all, he accepts the principled division between musar and halacha, meaning that these are separate systems, and he claimed that despite this, they are intertwined with each other to a certain extent. Is this really a disagreement? Do you think that halacha has no influence on morality and vice versa? I would appreciate it if you could point out the point of disagreement, if it exists.
thanks!
