Total War and Siege? Fair?

I think that total war and siege is fair because it is not the Union's fault that the people who were civilians who live in the south are for the Confederate. Total war and siege is fair because the southerners picked their side and they are going to get what they asked for. Also Sherman and Grant did what was right because if they wanted to win the war they would do what they thought was right. Also the southern civilians are doing what they think is right but that doesn't always mean safe. Also sometimes playing it safe doesn't mean its the right thing.
