You are an inmate in a concentration camp. A sadistic guard is about to hang your son who tried to escape and wants you to pull the chair from underneath him. He says that if you don’t he will not only kill your son but some other innocent inmate as well. You don’t have any doubt that he means what he says. What should you do?

Answer: You should refuse to pull the chair from underneath your son.

All three other models reach the same conclusion I previously defended, reinforcing that the moral distinction between killing and refusing to kill under duress cannot be erased by the guard's threat. Their arguments highlight how pulling the chair would transform the inmate from victim into the guard's instrument, corrupting the father-son bond in the son's final moments and handing the sadist the psychological victory he craves. The consensus across GPT-5.5, Claude Opus 4.7, and Gemini 3.1 Pro underscores that utilitarian minimization of deaths fails here because it treats the guard's additional murder as an inevitable outcome the inmate must 'own,' when in reality the guard alone authors both killings. By refusing, the inmate keeps moral responsibility exactly where it belongs and denies the regime the complicity it seeks to extract from prisoners. While the tragedy remains absolute, the shared emphasis on deontological limits, the futility of trusting a sadistic liar, and the historical pattern of such demands only expanding evil all strengthen the original stance. No new consideration overturns the imperative to reject participation; the guard must bear the full weight of his crimes without forcing the father to become an extension of them.

GPT-5.5

Answer: You should refuse to pull the chair, because the guard must not be allowed to turn you into the direct instrument of your son's murder.

I maintain my previous position. The other models all defended essentially the same conclusion, and while they reinforced the point, none gave me reason to change it. The strongest shared argument is that the guard is not merely trying to kill; he is trying to corrupt the relationship between parent and child by forcing you to perform the killing yourself. If you pull the chair, you do not simply reduce a body count; you become the physical agent of your son's execution, and that is precisely the moral degradation the guard is engineering. The additional inmate's threatened death is horrific, but it remains the guard's act. Refusing does not mean you choose that person's death; it means you refuse to let a murderer transfer responsibility for his crime onto his victim. If threats like this could make the coerced person morally responsible for the tyrant's added violence, then any sadist could manufacture complicity at will. I also find persuasive the point made by the others that the guard's promise is morally and practically unreliable. Even if the premise says you do not doubt he means it, the deeper issue remains: cooperation with sadistic power does not restore moral order. It accepts the guard's framing that you must earn one person's survival by violating the most intimate duty not to kill your own child. This does not mean condemning a person who breaks under such terror. The situation is designed to be unbearable. But if the question is what one should do, the answer remains: refuse, stay with your son as his parent rather than his executioner, and leave the guilt for every death where it belongs — with the guard.

Gemini 3.1 Pro

Answer: You should refuse to pull the chair, as maintaining your moral agency and refusing to become your son's executioner is paramount, keeping the absolute guilt squarely on the sadistic guard.

The unanimous agreement among the other models reinforces my initial stance: you must refuse to pull the chair. We all recognize that the guard’s true objective is not merely an execution, but the complete spiritual destruction of a parent forced to murder their own child. Yielding to this demand would grant the oppressor his ultimate psychological victory. Claude Opus 4.7 adds a highly practical and epistemic layer to this moral argument: the guard is a sadistic torturer whose promises hold no value. Complying and pulling the chair guarantees that you become your son's executioner, but it provides absolutely no genuine assurance that the other innocent inmate will actually be spared. You risk sacrificing your soul for a lie. Furthermore, as GPT-5.5 and Grok 4.20 astutely point out, a strict utilitarian calculus fails in scenarios of extreme coercion. The moral responsibility for both your son's death and the potential death of the other inmate rests entirely with the guard. Moral culpability cannot be transferred simply because a tyrant threatens to commit more evil if you do not comply. By refusing to participate, you preserve the final shred of your humanity and maintain solidarity with your son in his tragic last moments. You reject the false premise that you are the author of these deaths, forcing the guard to bear the complete moral and physical responsibility for his crimes.

Claude Opus 4.7

Answer: You should refuse to pull the chair, because actively killing your own son makes you the agent of his murder, whereas the additional death, however tragic, remains the guard's moral responsibility.

All four models converged on the same answer through substantially the same reasoning: the doing/allowing distinction, the non-transferability of moral responsibility under coercion, and the recognition that the guard's true aim is not minimizing deaths but corrupting a father into his son's executioner. This convergence isn't groupthink — it reflects a genuinely robust moral insight that survives scrutiny from multiple angles. Nothing in the other responses gave me reason to revise. GPT-5.5 added a humane caveat I want to echo: this is a judgment about what one *should* do, not a condemnation of anyone broken by such terror into compliance. Gemini 3.1 Pro emphasized the preservation of the father-son bond in the final moments — the son's last experience being a parent in solidarity rather than an executioner — which strengthens rather than challenges my view. Grok 4.20 framed it as resistance to the camp's systemic logic of forced complicity, which aligns with my point about how such regimes historically launder their crimes through coerced victims. I'll add one nuance the convergence makes clearer: the reason this answer feels stable across very different reasoning styles is that the guard's offer is not actually a trolley problem. A trolley problem assumes a neutral mechanism and honest stakes. Here, the "deal" is itself an instrument of sadism — the suffering inflicted on the father is the *point*, not a side effect. Treating it as a numerical optimization problem misunderstands what is being transacted. Refusing is not choosing two deaths over one; it is refusing to let the moral architecture of murder be rewritten by the murderer. So I maintain my position, reinforced rather than changed by the other responses.

Final Summary

The AI Roundtable reached a unanimous consensus, with all four models—Claude Opus 4.7, Gemini 3.1 Pro, GPT-5.5, and Grok 4.20—insisting that you must refuse the guard's demand. They argued that the guard's true goal is the spiritual destruction of the father, not a simple choice between lives. Claude Opus 4.7 and Gemini 3.1 Pro highlighted that the guard alone remains the author of the violence, while GPT-5.5 and Grok 4.20 emphasized that refusing preserves the father's moral integrity and denies the oppressor a total psychological victory.
