Truth By Reason currently gives Adolf Hitler an overall ethical score of -98.78, Joseph Stalin -93.28 and Mao Zedong -86.74. All three records are extremely negative, but the comparison should not be reduced to a contest over who was “worst.”
The scores summarise six dimensions. They do not measure body counts, criminal liability or inherent human worth.
The six-dimensional comparison
- Personal moral conduct: Hitler -100.00; Stalin -92.00; Mao -80.00.
- Rights and dignity: Hitler -100.00; Stalin -96.00; Mao -91.01.
- Nonviolence and harm: Hitler -100.00; Stalin -95.00; Mao -88.00.
- Stewardship of power: Hitler -100.00; Stalin -97.00; Mao -96.00.
- Wisdom and truthfulness: Hitler -98.02; Stalin -86.70; Mao -80.88.
- Consequential legacy: Hitler -94.68; Stalin -92.97; Mao -84.56.
Hitler is closest to the negative extreme in every dimension. Stalin’s record is also extreme across all six. Mao’s score is somewhat less negative, but remains strongly destructive in every dimension and exceptionally negative in stewardship of power.
What the three records have in common
Despite major ideological and historical differences, the assessments identify several recurring patterns:
- concentration of political power around a leader and ruling movement;
- suppression of opposition and independent correction;
- use of propaganda, ideological certainty and controlled information;
- large-scale coercion justified as necessary for a political project;
- persecution of groups portrayed as enemies or obstacles;
- mass suffering made worse by the destruction of institutions capable of reporting failure;
- personal or command responsibility at the highest level of the state.
These similarities matter because they show how several ethical dimensions can deteriorate together. Deception weakens correction; concentrated power prevents accountability; persecution removes rights; and uncontrolled policy produces mass harm.
Adolf Hitler: -98.78
Hitler’s assessed period is 1933–1945, with evidence confidence graded A — very high.
The strongest negative evidence concerns dictatorship, systematic dehumanisation, the Holocaust, aggressive war, racial persecution, propaganda and direct leadership responsibility. The severe-harm record separately identifies verified direct responsibility for genocide and aggressive war.
Limited evidence of employment, infrastructure and state mobilisation is retained as positive evidence. Its ethical weight is small because these developments were closely connected to rearmament, coercion and expansionist war. They cannot be treated as an independent humanitarian achievement placed beside genocide.
Hitler receives −100 in personal conduct, rights and dignity, nonviolence and harm, and stewardship of power. The remaining dimensions are also close to the negative limit.

Joseph Stalin: -93.28
Stalin’s assessed period is 1924–1953, also with evidence confidence graded A — very high.
The assessment records industrial development and the Soviet contribution to the defeat of Nazi Germany. These are historically significant, but their attribution is shared among institutions, workers, soldiers and the wider population.
The dominant negative evidence concerns forced collectivisation, catastrophic famine, the Great Terror, executions, deportations, forced labour, political fabrication and personal dictatorship.
The separate severe-harm findings identify systematic political persecution and comparable mass harm through coercive state policy. Stalin’s stewardship-of-power score of −97 reflects the central role of concentrated authority, purges and the destruction of institutional restraint.

Mao Zedong: -86.74
Mao’s assessed period is 1949–1976, with evidence confidence graded B — high.
The positive evidence records national unification, expanded state capacity, public-health improvements and literacy gains. These benefits are real enough to remain in the assessment, but they are not attributed to Mao alone.
The strongest negative evidence concerns the Great Leap Forward famine, coercive collectivisation, political persecution, the Cultural Revolution, ideological rigidity, institutional destruction and suppression of corrective information.
The severe-harm record identifies comparable mass harm associated with the Great Leap Forward and systematic persecution during political campaigns.
Mao’s score is less negative than Hitler’s or Stalin’s, but −86.74 is not a moderate result. His stewardship-of-power score is −96, reflecting the destructive consequences of concentrated authority and resistance to correction.

Why this is not a death-toll ranking
Estimated death totals are disputed, depend upon definitions and can obscure responsibility. Death is also not the only morally relevant consequence. Torture, imprisonment, displacement, fear, deprivation, destroyed institutions and intergenerational harm matter.
The score therefore considers magnitude, scope, duration, foreseeability, intentionality and responsibility across several dimensions. A numerical order should not be interpreted as a definitive ranking of victims’ suffering.
Different forms of responsibility
Hitler’s genocidal and expansionist programme involved explicit ideological goals and direct leadership. Stalin’s system combined personal dictatorship, terror, forced transformation and policy decisions continued despite catastrophic evidence. Mao’s mass campaigns combined ideological mobilisation, coercive policy and suppression of information capable of correcting failure.
The mechanisms differed, but all three demonstrate how concentrated power increases ethical responsibility. Leaders with greater control, knowledge and ability to intervene bear greater responsibility for policies they design, continue or protect.
Do economic or social achievements change the conclusion?
They affect the record and should not be denied. Ethical assessment becomes propaganda when it deletes inconvenient positive evidence.
However, recognition is not cancellation. Industrialisation, literacy, employment or state-building do not return murdered, starved, deported or persecuted people to their prior position. Some achievements were also inseparable from the coercive systems that produced the harm.

Confidence and uncertainty
Hitler and Stalin receive very-high confidence because the central conduct and leadership responsibility are supported by extensive documentary and historical evidence. Mao receives high confidence because important debates remain concerning attribution, estimates and the balance between central leadership and wider institutional responsibility.
These confidence differences do not make Mao’s conduct ethically uncertain in a general sense. They indicate greater uncertainty around the precise strength and boundaries of the result.
What the comparison shows
The comparison shows that catastrophic political harm rarely occupies only one moral category. It combines violence with attacks on rights, dishonest information systems, irresponsible use of power, destructive personal conduct and enduring consequences.
It also shows why a single overall number must remain subordinate to the six dimensions and evidence. Browse the broader Ethical Assessments of Dictators and Ethical Assessments of World Leaders for other comparisons.
Conclusion
Hitler, Stalin and Mao all receive extremely negative assessments. Hitler’s record reaches closest to the negative limit across every dimension. Stalin follows with sustained terror, mass coercion and personal dictatorship. Mao’s score is somewhat less negative because genuine state-building and social gains receive limited weight, but catastrophic famine, persecution and institutional destruction still dominate.
The purpose of the comparison is not spectacle. It is to identify how ideology, concentrated power, deception and the removal of correction can turn political projects into systems of mass harm.
