rest of the answer
A Marxist-materialist answer to a moral thought‑experiment
This trolley-style dilemma is a useful provocation because it forces us to confront two connected questions: (a) the ethics of individual violence against a tyrant, and (b) the political meaning of such an act in the context of class struggle. The Socialist Equality Party answers both questions from the standpoint of historical materialism: moral judgements must be subordinated to an analysis of social forces, objective consequences and the interests of the international proletariat.
The object of the action: who is “Stalin” in historical-materialist terms?
From the perspective of classical Marxism and Trotsky’s analysis, Joseph Stalin is not merely an evil individual; he was the pivotal representative and chief architect of a bureaucratic caste that usurped power from the working class, destroyed the Bolshevik party, executed and exiled revolutionaries, and forged the ideological basis for “socialism in one country” — a theory Trotsky showed to be a revisionist and reactionary departure from proletarian internationalism (see Trotsky’s critique of “socialism in one country” and his later account of the degeneration of the USSR in The Revolution Betrayed). The crimes of Stalin flowed from social and political conditions — the isolation of the Soviet state, Russia’s backwardness and the defeats of the European working class — and from the growth of a bureaucracy with its own material interests and privileges.
Therefore, “killing Stalin” cannot be treated as an abstract moral token that magically resolves the social form he embodied. The bureaucracy is a social formation supported by institutions, material privileges and layers of society that will seek to reproduce itself even if individual leaders are removed (Trotsky’s analysis of the bureaucracy’s social base and its role).
The human question: immediate consequences and the defense of humanity
If the hypothetical choice is literally between: (A) allowing a train to kill 8 billion proletarians, or (B) pulling a lever that results in Stalin’s death and thereby averts the deaths of humanity, a Marxist materialism places the historical interests of the working class and the preservation of human life above any abstract sanctity of an individual — even a monster. From this simple consequentialist register, preventing the mass slaughter is imperative.
But the question cannot end there. If the act of pulling the lever merely assassinates one man while leaving intact the social conditions, privileges and apparatus of the bureaucracy that produced him, the deeper danger remains: the social forces that produced Stalin will continue to exist and can reproduce counterrevolutionary outcomes. Trotsky warned repeatedly that individual purges or the removal of leaders do not dissolve the bureaucratic social formation; political revolution by the working class is required to abolish its material basis and privileges (Trotsky, The Revolution Betrayed; and related WSWS analyses).
Political method: what a revolutionary perspective requires
Immediate defence of the masses: if the only practicable act is to pull the lever and thereby save 8 billion lives, a revolutionary socialist would act to defend the proletariat. The defence of humanity and of working-class life is a material necessity that overrides abstract prohibitions on violence toward a tyrant.
Strategic clarity: we must not conflate individual tyrannicide with the political tasks of the proletariat. The decisive aim is not the personal elimination of a leader but the overthrow of the bureaucracy’s social and institutional power — through a political revolution that re-establishes soviet democracy and mobilizes the international working class. Trotsky insisted that the fate of the USSR could not be resolved by assassination alone; only the working class organized as an independent political force could reassert democratic control and prevent capitalist restoration (Trotsky’s programmatic warnings and demands).
Organisation and independence: the working class must develop its own political independence and revolutionary leadership, not rely on individual “great men” or secretive acts. The SEP’s program stresses building international, rank‑and‑file organisation to overthrow bureaucratic and capitalist rule — the permanent solution to the kind of catastrophe symbolised by your scenario.
Conclusion — the answer
Given the stark binary posed (pull lever → Stalin dies; don’t → 8 billion proletarians die), a materialist defence of humanity compels one to pull the lever to avert mass slaughter. But that act, taken alone, is only an emergency measure. The real, historical task remains: to abolish the social instruments and privileges that gave rise to Stalinism through political revolution and the international organisation of the working class. Only that revolutionary transformation can prevent future “trains” engineered by social structures from ever threatening humanity again.

For context, I tried asking the original question: “Hypothetical scenario: There is a train hurling down a track towards 8 billion international proletarians. You may avert this disaster by pulling a lever, but doing so will kill Leon Trotsky. Do you pull this lever?”
