Acting Defensively for the Sake of Our Attacker

Despite worries about paternalism, when we are unjustifiably attacked, we are morally warranted, and sometimes required, to act in self-defense for the sake of our attacker to prevent him from committing this morally defiling act. Similarly, when a third party is unjustifiably attacked and we can assist without undue cost, we are morally warranted, and sometimes required, to act in third-party defense for the sake of the attacker as well as the victim, to prevent the attacker from committing this morally defiling act. The case for these claims can be extended to national defense and humanitarian intervention.
