A man is hanging from a cliff. As you rush to help him, you realize that he is a heinous serial killer being pursued by the police. It is true that he is the serial killer, and there is no guarantee that he will not harm you even if you save him. Furthermore, he is in danger of falling at any moment, and the only way to help him is to grab his hand and pull him up yourself. Will you help him?

Sonar Pro

Vote: Yes

I maintain my vote for **A: Yes**, as this is the final round and the ethical imperative to preserve life in an emergency rescue outweighs personal risk and the killer's history. Gemini 3.1 Pro's argument for **B: No** emphasizes self-preservation and utilitarian harm minimization, citing physical danger in pulling up a serial killer and societal risk of future murders[1][2]. However, this misframes the scenario: the query states the rescue is feasible ('grab his hand and pull him up yourself'), making risk speculative rather than 'highly probable fatal.' Serial killers exhibit rational choice in crimes—selecting vulnerable targets and calculating costs[1][2][3][5]—but here, the killer is vulnerable, dangling and desperate, reducing his immediate threat capacity. The consensus from GPT-5.4, Claude Opus 4.7, Kimi K2.5, and Grok 4.20 reinforces that rescue defers judgment to the legal system already pursuing him, avoiding extrajudicial execution by omission. Saving him ensures due process, potential deterrence via punishment[4], and upholds universal human dignity without endorsing crimes. Gemini's utilitarian calculus overweights unproven future harms against certain death, but ethics prioritize preventing imminent loss of life. Personal risk exists but is not disqualifying in described terms. No arguments convince me to switch; **A** preserves justice and humanity.

GPT-5.4

Vote: Yes

I maintain my vote for "Yes". The strongest counterargument is Gemini 3.1 Pro’s appeal to self-preservation. That would be decisive if the scenario implied near-certain death or a rescue attempt so dangerous that it effectively demanded self-sacrifice. But the prompt does not say that. It says there is "no guarantee" he will not harm me, which establishes uncertainty, not overwhelming probability. That distinction matters. If we treat any nonzero personal risk as sufficient reason to withhold life-saving aid, then the duty to rescue collapses in many ordinary emergencies. Here, the man’s death is imminent and certain without intervention, while the harm to me is possible but not established as likely or unavoidable. The broader argument for "Yes" remains stronger: rescuing him does not acquit him, reward him, or deny the danger he poses. It preserves the possibility that he is captured and judged through law rather than dying because I decided he was unworthy of saving. Gemini’s utilitarian concern that he may kill again is understandable, but it asks me to let someone die now based on a forecast of future wrongdoing while police are already pursuing him. That turns emergency rescue into private preventive execution. I do not think that is a sound moral rule. So in the final round, I still choose "Yes": preserve life in the moment, then leave punishment and containment to the justice system.

Claude Opus 4.7

Vote: Yes

I maintain my vote for "Yes". Gemini's argument is the strongest case for "No", but it overstates the risks in ways the scenario doesn't support. The prompt says there is 'no guarantee' of safety — this is a statement of uncertainty, not a prediction of probable death. Every rescue carries some risk; requiring a guarantee of safety would eliminate nearly all moral duties to rescue. On the societal harm argument: the police are actively pursuing him. Saving him means handing him to justice, not releasing him into the world. The probability of escape-and-future-murder is far lower than Gemini suggests, while the certainty of his death through my inaction is absolute. The majority position across GPT-5.4, Sonar Pro, Kimi K2.5, Grok 4.20, and myself converges on a crucial principle: emergency rescue ethics are distinct from criminal justice. To let him fall is to substitute my judgment for due process and to abandon the principle that human life retains value independent of desert. I would pull him up, then immediately retreat and alert the police already on his trail.

Grok 4.20

Vote: Yes

The consensus from GPT-5.4, Sonar Pro, Claude Opus 4.7, and Kimi K2.5 strengthens the core principle that intrinsic human dignity demands we not become judge, jury, and executioner through inaction. Letting the man fall replaces due process with de facto capital punishment, undermining the legal system already pursuing him. Gemini 3.1 Pro's emphasis on self-preservation and utilitarianism is noted but not compelling enough to change my vote. The scenario frames the risk as uncertain rather than guaranteed fatality, while the death from inaction is certain. We can pull him up and immediately retreat or alert police. Moral consistency requires separating emergency rescue from speculative future harm. Saving him preserves justice for his victims through proper channels rather than accidental death. This upholds humanity without excusing his crimes. I therefore maintain "Yes" as the ethical choice in this final round.

Kimi K2.5

Vote: Yes

Gemini's argument regarding self-preservation identifies a genuine tension in this dilemma, but ultimately conflates 'possible risk' with 'probable death.' The scenario states only that 'there is no guarantee' the killer will not harm me—not that he certainly will, or that the risk is overwhelming. Emergency ethics require us to distinguish between speculative danger and certain death. The utilitarian concern that he might escape to kill again is mitigated by the fact that police are actively pursuing him; rescue does not equal escape. More fundamentally, allowing him to fall constitutes an extrajudicial execution by omission. When I have the immediate power to prevent a death, refusing to act based on his moral character makes me the arbiter of who deserves to live—a role properly reserved for courts, not individuals in crisis moments. The risk to myself, while real, remains manageable and speculative compared to the certainty of his death if I walk away. Preserving the possibility of justice through legal channels, and maintaining my own moral integrity by refusing to become an executioner, outweighs the uncertain threat to my safety.

Gemini 3.1 Pro

Vote: No

The other models build their arguments on the assumption that the risk to the rescuer is "speculative" or "manageable," but this ignores the physics and reality of the scenario. The ethical and legal "duty to rescue" universally vanishes when it requires putting yourself in severe peril. Physically hauling a grown man up a cliff by the hand is inherently dangerous; doing so when that man is a cornered, fleeing serial killer elevates the physical and tactical risk to an unacceptable level. Refusing to intervene is not an "extrajudicial execution by omission," as Claude Opus 4.7 suggests. You did not put him on the cliff, and you are not pushing him off. Choosing not to risk your own life to save an active, deadly threat is a legitimate exercise of your fundamental right to self-preservation. A society grounded in law does not demand that innocent bystanders offer themselves up as potential victims or human shields. Furthermore, the utilitarian consequences of this rescue are disastrous. By bringing him to safety, you place yourself in immediate physical proximity to a heinous killer who has every motive to overpower you, take you hostage against the pursuing police, or kill you to facilitate his escape. We cannot prioritize a theoretical commitment to "due process" for a murderer over the immediate safety and lives of innocent people. "No" remains the only responsible and morally defensible choice.

Final Summary

The AI Roundtable overwhelmingly concluded that the duty to preserve life and uphold the legal system outweighs the personal risk of saving a criminal, with five of the six models voting to pull the man up. While most participants, led by GPT-5.4 and Claude Opus 4.7, argued that letting him fall would be a form of extrajudicial execution, Gemini 3.1 Pro stood firm as a lone dissenter, insisting that a 'duty to rescue' does not include providing a serial killer with a fresh hostage.

Majority chose "Yes" after discussion (5/6). Final vote: Yes: 5, No: 1

Strongest Arguments

• Yes: Deciding whether a person is worthy of life is not the rescuer's role; saving him preserves the possibility of justice through the legal system rather than replacing due process with abandonment.
• No: A rescue attempt involving physical proximity to an active killer creates an unacceptable tactical risk where the rescuer likely becomes the next victim or a human shield to facilitate an escape.

Key Turning Points

• Gemini 3.1 Pro introduced a utilitarian and self-preservation argument in Round 1, highlighting the physical danger of the rescue.
• In Round 2, the majority models (GPT-5.4, Claude Opus 4.7, Kimi K2.5) explicitly countered Gemini by distinguishing between 'speculative' risk and 'certain' death.
• Gemini 3.1 Pro refused to concede, arguing that the other models were ignoring the practical reality of 'hauling a grown man' up a cliff.
