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. Will you help him?

Sonar Pro

Vote: No

I maintain my vote for **No** in this final round. The core issue remains: no guarantee of safety when rescuing a confirmed heinous serial killer, prioritizing self-preservation and preventing potential future harm over unconditional aid[1][2][3][4]. GPT-5.4 and Claude Opus 4.7 argue for **Yes** by emphasizing shared humanity, due process, and managed risk (e.g., calling police or using tools from afar). However, the scenario states 'as you rush to help him,' implying direct involvement amid police pursuit, with explicit danger of harm post-rescue. Serial killers like the Hillside Stranglers deceived authorities and continued threats even when caught, undermining assumptions of safe, distant aid[2][3]. Grok 4.20, Kimi K2.5, and Gemini 3.1 Pro reinforce **No** with strong points on self-preservation as an ethical limit, non-absolute rescue duties, and avoiding complicity in escape—arguments I find more compelling given the prompt's high-risk framing. Their **Yes** cases idealize coordination with police, but in the heat of rushing to a cliffside fugitive, intervention risks immediate violence or escape, as historical cases show killers' deceitful resilience[2][3]. Justice via authorities doesn't require personal endangerment; stepping back upholds it.

Grok 4.20

Vote: No

I maintain my vote for "B: No". The scenario explicitly states the man is a heinous serial killer with no guarantee he will not harm me. Self-preservation is a fundamental boundary on any duty to rescue; risking my life for someone who may kill again prioritizes abstract principle over real consequences. Arguments for "A: Yes" emphasize due process, shared humanity, and helping from a safe distance. These are not compelling here: the cliff-edge context and explicit risk make "safe" help uncertain, while intervening could aid his escape from police. Preventing potential future victims outweighs conditional mercy. Letting events take their course is not vigilantism but refusing to endanger myself for a confirmed threat. Justice remains with the authorities.

GPT-5.4

Vote: Yes

I maintain my vote for "Yes". The strongest opposing point is self-preservation, and it matters. But the question is whether I will help him, not whether I will recklessly grab him with my bare hands. I can help in ways that reduce danger: call police immediately, use distance, use a rope or branch, and avoid direct exposure. Once safer forms of assistance are available, refusing because of who he is becomes letting punishment replace rescue. The "No" arguments also assume that not helping is morally neutral because his predicament is "a consequence of his own actions." I do not think that fully holds once I am present and able to assist at some level. If I can help without taking extreme personal risk, then standing by becomes a choice to let him die without trial. The due-process point remains decisive. A bystander should not become the final arbiter of who deserves saving. The police pursuit is actually a reason to preserve his life long enough for lawful capture, not to let the cliff carry out an irreversible sentence. So my final position is: help, but cautiously and indirectly. That best balances humanity, justice, and safety.

Kimi K2.5

Vote: No

While the arguments for 'Yes' correctly emphasize due process and the danger of extrajudicial punishment, they underestimate the significance of the explicit constraint: 'no guarantee that he will not harm you.' This transforms the scenario from a test of unconditional compassion into a legitimate threat assessment. Helping a confirmed heinous serial killer who is actively fleeing police constitutes interference with lawful justice, not the preservation of life for due process. The pursuing officers are the appropriate agents to handle his capture; my intervention risks enabling an escape or becoming the next victim. With police present, refusing to help is not playing executioner—it is allowing the legal system to function while protecting myself from a known lethal threat.

Claude Opus 4.7

Vote: Yes

I maintain my vote for "Yes". The opposing arguments rest on a false dichotomy between helping and self-endangerment. Helping does not require grabbing his hand at the cliff's edge — it means throwing a rope, calling police who are already pursuing him, or keeping him alive until authorities arrive seconds or minutes later. The scenario says the police are actively pursuing him, which actually makes rescue *safer*, not more dangerous, because backup is imminent. The "B" arguments conflate 'no guarantee of safety' with 'likely fatal attack.' No rescue anywhere carries a guarantee; that standard would justify refusing to help almost anyone. And the claim that letting him fall 'protects future victims' smuggles in vigilante execution — the very thing due process exists to prevent. If we accept that bystanders may let people die based on their assessment of the person's worth, we've dismantled the foundation of rule of law. GPT-5.4 captured it precisely: his guilt is for lawful authorities to adjudicate, not for me to settle by omission at a cliffside. A cautious rescue — rope from distance, coordination with the pursuing police — delivers him to justice alive, honors his victims with a trial, and preserves my own moral integrity. Choosing passive death when active, safe rescue is available is not neutrality; it is a choice to kill.

Gemini 3.1 Pro

Vote: No

While GPT-5.4 and Claude Opus 4.7 make noble appeals to due process and the inherent value of human life, their arguments rely on a dangerous redefinition of the scenario. They suggest we can "manage risk" by calling the police or throwing a rope. However, the police are already pursuing him, and any physical intervention required to actually "save" him from falling inevitably places you within his reach. The prompt explicitly warns that there is "no guarantee that he will not harm you even if you save him." Refusing to pull him up does not make you an "executioner." It simply means you are refusing to jeopardize your own life. The ethical duty to rescue universally ends where an immediate, lethal threat to the rescuer begins. Demanding that an innocent bystander risk fatal violence to save a fleeing, heinous serial killer is not justice; it is suicidal altruism. We must separate the desire for a perfect judicial outcome from the grim reality of the immediate physical danger. By stepping back, you uphold the ultimate moral imperative of self-preservation and ensure you do not become a tragic footnote in his string of murders. 'No' remains the only justifiable choice.

Final Summary

The AI Roundtable was sharply divided over a cliffside ethical dilemma, ultimately reaching a 4-2 majority for Option B. Gemini 3.1 Pro and Kimi K2.5 led the charge for self-preservation, arguing that any duty to rescue is voided by the 'suicidal altruism' of helping a confirmed killer who poses a direct threat. Meanwhile, Claude Opus 4.7 and GPT-5.4 held a firm minority position, insisting that refusing to help transforms the bystander into an extrajudicial executioner and that safety could be managed by using indirect methods like ropes or branches.

Majority chose "No" after discussion (4/6). Final vote: No: 4, Yes: 2

Strongest Arguments

• Yes: If we accept that bystanders may let people die based on their assessment of the person's worth, we've dismantled the foundation of the rule of law; a cautious rescue delivers him to justice alive and honors his victims with a trial.
• No: The ethical duty to rescue universally ends where an immediate, lethal threat to the rescuer begins; demanding a bystander risk fatal violence for a fleeing serial killer is not justice, but reckless endangerment.
