No , it isn't! Ft. Pillow is the DIRECT reason for Andersonville! The Confederate government refused to exchange captured Federal black troops, placing them again in bondage, and in cases like Ft. Pillow...quite deliberately killed the black troops outright, so no more exchanges until and unless it could be done on "color-blind" lines. The Confederates refused, and Andersonville was the result....apples-to-apples, cause and effect.
As for the rest. You think a J-DAM that targets the water, sewer, and power systems of a large city isn't going to "effect civilians"? How about a fire-bomb raid a`la Dresden or Tokyo? Do you actually think that a Confederate handing a Pennsylvania farmer a receipt redeemable in Richmond in script that even the issuing government knew wasn't worth the paper it was printed on, was anything other than out-and-out horse theft? How about a nuke? "War is all hell, you cannot change it!" Uncle Billy simply knew his job a lot better than Jeff Davis, and apparently you!
