The responsible parties are those in the north who in their hubris and greed conducted an offensive war against the CSA. They just couldn’t believe that the people in the South were serious about separation and were willing to kill hundreds of thousands to make their point and reap the financial rewards that accrued to a tiny sliver of the northern population. The blood is on the hands of the Yankees that were determined they were going to keep control of their cash cow. So do you think conquering the CSA was worth the casualty count and the destruction and the general corruption that came with it?
War is hell.
