What Judaism Teaches About Killing in Self-Defense
Jewish law is perhaps the most emphatic of the three traditions on self-defense. The Talmudic principle 'if someone comes to kill you, kill him first' (Sanhedrin 72a) is a binding legal obligation, not merely a permission. This derives from the broader principle of pikuach nefesh (saving a life), which overrides virtually all other commandments. Self-defense is not only allowed — it is a moral duty.

- All traditions: If you carry a weapon for self-defense, ensure you are trained, responsible, and prepared to use proportional force only as a last resort.
