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.

- Jewish: Pikuach nefesh (preserving life) is among the highest values in Jewish law. Self-defense is not merely excused — it is commanded when innocent life is at stake.
- 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.
Repentance: Teshuvah
The Talmud teaches that teshuvah was created before the world itself — Hashem believed in your return before you were born. The gates of return are open now.

Is killing in self-defense considered murder?
No.
No. In all three Abrahamic traditions, killing in legitimate self-defense is distinguished from murder. Murder is the unjustified taking of innocent life. Self-defense protects innocent life from unjust aggression. The intent matters: self-preservation vs. malice.
What about 'turn the other cheek' (Matthew 5:39)?
Scholars debate this passage.

How much force is allowed in self-defense?
All three traditions emphasize proportionality.
All three traditions emphasize proportionality. You may use the minimum force necessary to neutralize the threat. Excessive force — continuing to attack after the threat is neutralized — would be sinful. The goal is to stop the threat, not to punish.
What if I could have fled instead of fighting?
Jewish law also prefers avoiding confrontation if there is a safe alternative.
Jewish law also prefers avoiding confrontation if there is a safe alternative. However, none require retreat if it would leave others in danger.
