If what you say is true - and you make a fair case - then we can dismiss the notion that the north was fighting for some high moral cause like “freeing the slaves.”
The slogan, “as he died to make men holy, let us die to make men free” can more rightly be seen - if you are correct - as a “moral” pretext for war by the north.
You are nothing if not a broken record. You routinely post this turd as if anyone here makes such a claim - no one does. It is entirely a red herring of your creation.
