Existential Self-Defense Ethics / 生存威胁下的自卫伦理

Definition

Existential self-defense ethics / 生存威胁下的自卫伦理 is the problem of what a person or community may do when it reasonably fears destruction but survival appears to require sacrificing outsiders, future members, or moral limits.

Current Synthesis

《进击的巨人》 makes the problem unusually severe because Titan power belongs to one population and cannot simply be shared into a stable balance. Fear is therefore not wholly invented, yet no proposed response converts vulnerability into a clean right. Zeke’s sterilization plan protects outsiders by ending a people through nonconsensual reproductive extinction; Eren’s Rumbling protects the island by destroying most outsiders; and the Scouts reject extermination without possessing a permanent solution.

The episode favors neither moral purity nor final solutions. A limited Rumbling used as deterrence may buy time, but it retains escalation, misperception, and future power-struggle risks. Refusal to commit atrocity can preserve a boundary while leaving one’s own people exposed. Ethical judgment must therefore distinguish understanding a survival motive from accepting necessity, proportionality, civilian destruction, and the claim that one generation may close history for all later generations.

The post-Titan continuation of war adds a decisive qualification: removing one feared capacity does not remove competition, identity, and enemy construction. A solution that claims permanent peace through weapon removal, self-erasure, or extermination overstates what one intervention can settle.

Key Claims

• A genuine survival threat makes violent options intelligible without automatically making them justified.
• Self-extinction and extermination both solve fear by denying a population’s future rather than building consent or trust.
• Refusing mass killing remains morally meaningful even when no safe alternative is available.
• Deterrence can buy political time but cannot guarantee stable trust or prevent later internal conflict.
• Civilian harm, proportionality, uncertainty, and future generations constrain claims of collective self-defense.
• Ending one weapon or enemy category does not end the human capacities that reproduce war.

Evidence

Three catastrophic responses

• 005 串台|《进击的巨人》又双叕完结了？到底烂尾没？ contrasts sterilization, the Rumbling, and the Scouts’ resistance as self-erasure, unlimited preventive defense, and morally bounded action without guaranteed survival.

Deterrence and political time

• 005 串台|《进击的巨人》又双叕完结了？到底烂尾没？ presents a limited Rumbling as a possible temporary deterrent while emphasizing that Titan power differs from broadly reproducible nuclear technology.

No permanent technical solution

• 005 串台|《进击的巨人》又双叕完结了？到底烂尾没？ notes that war continues after Titan power disappears and that surviving Eldians could still contest concentrated power among themselves.

Counterevidence & Qualifications

The concept is derived from fictional extremes and cannot by itself settle real cases. Whether a threat is imminent, alternatives are feasible, deterrence is credible, civilians can be distinguished, or force is proportionate requires evidence outside the analogy. Titan power differs materially from nuclear weapons and ordinary military capacity. Describing an option as “least bad” reconstructs a decision problem; it does not prove necessity or excuse atrocity.

What Changed

• Created a framework separating survival motive from unlimited moral permission.
• Treated self-erasure, extermination, deterrence, and constrained resistance as distinct rather than interchangeable solutions.
• Added the limit that removing a weapon does not remove the political causes of conflict.
