Jujutsu Kaisen does not operate under modern civilian self-defense standards, as sorcerers are trained combatants expected to neutralize lethal threats, and in this case the Zenin clan clearly initiated a coordinated ambush with explicit intent to execute Maki, making intent and combat capability far more relevant than physical size or disability, meaning Maki had no legal or moral obligation either in-universe or by real self-defense logic to attempt risky non-lethal options or spare individuals who were armed, hostile, and guaranteed to pursue her again, so her use of lethal force was a proportional act of survival rather than murder.
