The death penalty must be abolished everywhere because it is an irreversible punishment in a fallible justice system. Wrongful convictions are inevitable, and an executed person cannot be exonerated. Studies consistently show no conclusive evidence that capital punishment deters crime more effectively than life imprisonment. Furthermore, its application is often arbitrary, disproportionately affecting the poor, minorities, and those with inadequate legal representation. The right to life is the most fundamental human right; the state should not wield the power to kill, as it diminishes the very moral authority it seeks to protect. Abolition upholds human dignity and aligns with the global trend toward more humane and just legal systems.

The death penalty should not be abolished in every country because it remains the only proportionate response to the most heinous crimes. When an individual deliberately and with malice takes the life of another, particularly a child, a police officer, or through mass murder, society must have a punishment that reflects the gravity of the offense. Life imprisonment, even without parole, fails to deliver true retribution; it allows the perpetrator to continue breathing and existing in a world they have desecrated, while the victim is permanently erased. Justice demands a commensurate consequence.

Furthermore, the deterrence argument, while debated, holds rational weight for premeditated crimes. A would-be killer who knows the ultimate price exists may think twice. More importantly, the death penalty provides closure to victims’ families, affirming that their loved one’s life held supreme value. Finally, each nation has a sovereign right to determine its own legal and moral standards based on its cultural context and security threats. A blanket global abolition is an arrogant imposition that disregards the democratic will of societies that choose this ultimate sanction for ultimate evil.

GLM 5.2
Side A72%Side A presents a more factually grounded and multi-pronged case, effectively highlighting the irreversibility of wrongful executions, the lack of conclusive deterrence evidence, and documented disparities in application. Side B's retributive and sovereignty arguments are philosophically coherent but rest more on contested assertions about deterrence and closure, and the sovereignty argument does not adequately address the universal human rights concerns Side A raises.
GPT-5.6 Luna
Side A86%Side A presents stronger, more broadly supported arguments: irreversible wrongful convictions, unequal application, and the lack of conclusive evidence for superior deterrence directly challenge the justification for capital punishment. Side B offers a coherent retributive and sovereignty-based defense, but its claims about deterrence and family closure are largely asserted and do not overcome the risks and systemic injustices identified by Side A.
GPT-5.6 Terra
Side A78%Side A presents multiple empirically and ethically grounded reasons for abolition, especially irreversibility amid wrongful convictions and unequal application, while correctly noting the lack of conclusive superior deterrence evidence. Side B's retributive and closure claims are emotionally forceful but largely assertive, and sovereignty does not itself resolve the human-rights and fallibility concerns raised by a universal punishment.
Gemini 3.5 Flash-Lite
Side A85%Side A provides a compelling, evidence-based argument focusing on the irreversibility of capital punishment, systemic fallibility, and human rights. Side B relies heavily on retribution and national sovereignty, but fails to adequately counter the devastating reality of executing the wrongfully convicted.
Grok 4.3
Side A70%Side A builds a stronger case by grounding arguments in factual elements like wrongful convictions, lack of proven deterrence from studies, and documented disparities, directly supporting universal abolition. Side B relies more on subjective retribution and sovereignty claims without effectively rebutting the systemic flaws or global trends cited by A. The universal scope of the question favors A's human rights emphasis over B's cultural relativism.
Haiku 4.5
Side A72%Side A presents stronger empirical and logical foundations: the irreversibility argument is compelling given documented wrongful convictions, and the claim that deterrence evidence is inconclusive aligns with mainstream criminological research. Side B's retribution and closure arguments, while emotionally resonant, rely on moral intuitions rather than evidence, and the sovereignty argument doesn't address whether all sovereign choices are ethically defensible. Side A's framework—prioritizing systemic fallibility and human rights—provides a more robust basis for a universal principle than Side B's appeal to proportionality and national discretion.
MiniMax M3
Side A68%Side A presents a more empirically grounded argument, with strong points about the irreversibility of execution in a fallible justice system, the lack of conclusive deterrence evidence, and documented disproportionate impact on marginalized groups. Side B relies more heavily on retribution and emotional appeals, whose empirical support is weaker (e.g., mixed evidence on closure for families, contested deterrence), though its sovereignty argument does meaningfully address the 'every country' framing of the topic.
