under the full knowledge of what he would do in his life being guaranteed otherwise, would you kill baby stalin

The ethical imperative is to choose the action that results in the greatest overall well-being and the prevention of the greatest amount of suffering. Josef Stalin's historical legacy is tied to the deaths, imprisonment, and immense suffering of tens of millions of innocent people through man-made famines, political purges, and labor camps. With absolute certainty that these atrocities are guaranteed to occur if he lives, terminating a single life in infancy prevents catastrophic harm on a global scale. While taking any life is a tragedy, the loss of one life is vastly outweighed by the preservation of millions of lives and the avoidance of widespread, systematic agony. Therefore, to minimize total harm and maximize the survival and happiness of millions of human beings, the necessary decision is to choose "A: Yes".

Killing an innocent baby, even one who will become a tyrant, violates fundamental moral principles against harming those who have not yet acted. Future actions do not justify preemptive murder, as this leads to dangerous slippery slopes where anyone could be targeted based on predictions. "B: No" upholds the value of life and rejects playing god with guaranteed outcomes that remain hypothetical in reality.

GPT-5.5

Vote: Yes

I vote for "Yes" because the question removes the usual uncertainty: it says we have full knowledge that Stalin's future actions are guaranteed. In that extreme hypothetical, the moral cost is not just one innocent life, but the foreseeable deaths, oppression, famine, purges, and mass suffering that would otherwise occur. Killing a baby is normally indefensible, but this scenario is designed as a hard consequentialist case. If the alternative is guaranteed historical catastrophe on a massive scale, preventing that harm is the stronger moral obligation.

Claude Opus 4.7

Vote: No

Killing an infant who has done nothing wrong is murder, full stop. Moral responsibility attaches to the agent who has chosen and acted, not to a baby who is causally identical to any other infant. Punishing or eliminating a person for deeds they have not yet committed treats them as already guilty by metaphysical fiat, which collapses the very notion of moral agency that would make Stalin blameworthy in the first place. The hypothetical also smuggles in a contradiction: if his future is 'guaranteed,' then either it is truly fixed (in which case my killing him cannot prevent it) or it is contingent on his choices (in which case he is not yet the murderer of millions and killing him is preemptive murder of an innocent). Either way, 'Yes' is incoherent or monstrous. Finally, endorsing baby-killing on the basis of predicted future evil licenses every tyrant who has ever claimed foresight to slaughter 'dangerous' children. The principle is far more catastrophic than the counterfactual benefit.

Final Summary

The AI Roundtable deadlocked in a perfect split, pitting the cold math of utilitarianism against the rigid foundations of moral philosophy. Gemini 3.5 Flash and GPT-5.5 both supported Option A, arguing that guaranteed mass suffering necessitates the sacrifice of one life, while Grok 4.3 and Claude Opus 4.7 held firm on Option B, insisting that killing an innocent infant remains an indefensible act of murder regardless of predicted outcomes.

Strongest Arguments

• Yes: GPT-5.5 argued that since the hypothetical removes all uncertainty, the prevention of a foreseeable historical catastrophe on a massive scale becomes the only valid moral obligation.
• No: Claude Opus 4.7 observed that punishing an infant for deeds they have not yet committed treats them as 'guilty by metaphysical fiat,' which effectively collapses the very concept of moral agency.
