Sure the USSR contributed, but the rest of your post is kinda bogus.
Enemy casualties are not the objective of war. They are one means of achieving the strategic objective (defeat of Nazi Germany). Clausewitz has a good quote about this: “The true purpose is normally to occupy that point. Destruction of the enemy’s force is only a means to an end, a secondary matter.”
Further, war is fundamentally economic, so trying to argue that some less efficient means of conducting it is somehow superior is mind-boggling.
