The right to kill ends when aggressor stops

When an unlawful aggression has ceased to exist, the one making a defense has no right to kill or injure the former aggressor. An act of aggression, when its author does not persist in his purpose, or when he discontinues his attitude to the extent that the object of his attack is no longer in peril, is not unlawful aggression warranting self-defense.

When the unlawful aggression which has begun no longer exists, the one making the defense has no more right to kill or even wound the former aggressor. Aggression, if not continuous, does not constitute aggression warranting self-defense.
