Yes. Parts of the Confederacy did.
They seceded, 11 of 13 to be exact. They said they were no longer part of "The United States" and they continued with their way of life which included the keeping of slaves and slave labor.
They didn't think it was wrong when they were part of it and sure as heck didn't think it wrong when they had seceded.
At least until Lincoln came out with his Emancipation Proclamation. And even then some slave owners- most plantations were destroyed by the Civil War- did not follow it. A few did though
The two ideas of total war was used because the countries against each other where angry with each other and It was one of the deadliest conflicts in history and precipitated major political change, including the Revolutions of 1917–1923 in many of the nations involved. Unresolved rivalries at the end of the conflict contributed to the start of the Second World War twenty-one years later. They wanted to end conflict. The second reason was that each country wanted more power. It was a "war to end all wars" But it never ended all wars since World War II Came around the corner twenty-one years later.
