Overall ethical score
+86.72
Reasoned summary
Nightingale combined care with evidence and institutional reform. Her greatest ethical achievement was converting compassion into systems that continued saving lives after her direct service ended.
This assessment presents six separate ethical dimensions rather than one overall moral score. Each result must be read with its evidence, plausible range, confidence, disputes, exclusions, severe-harm findings and sources.
Most significant negative evidence
The score is moderated by paternalistic Victorian assumptions, a military-imperial setting and disputes over the precise share of wartime mortality reduction attributable to her own interventions.
