Abstract

Responsibility to Protect (R2P) doctrine assumes that there exists an underlying humanitarian duty to forcefully intervene in situations where innocent human lives are threatened with unjust violence. But what is the philosophical basis for the humanitarian moral obligation that underpins the R2P doctrine? I demonstrate that a third party should use forceful intervention (which might include lethal force) to protect an innocent human life in cases where the intervener has a duty to rescue the potential victim’s life and the use of force is morally permissible. Then I argue that a potential intervener is permitted to kill the attacker when he has an impartial reason for doing so: the attacker is unjustly threatening an innocent person’s life. Impartial justification is important in such cases, I argue, because it affirms the equality of all humans: that one human is not worth intrinsically more than another.
