Was it necessary or justified?

I personally do think using siege and total war was necessary to accomplish the Anaconda Plan, which would play a huge role in winning the war. It had a huge impact and definitely was close to breaking the will of the South. They were successful in controlling Vicksburg and stopping any resources from coming into the South. However, I do not think it was right. Families lost homes and possessions that were very dear to them. Innocent civilians were killed and STARVED TO DEATH. It was cruel and harsh, like torturing someone as they slowly die. I know I may sound confusing, but what I'm trying to say was that it was wrong, but was necessary to win the war.
