Bobert, you're changing the scenario again. If the guy's armed, then he's a threat to you and your family, and you kill him, rather than A)reasoning with him until he kills you all or B) running away and letting him rape and kill your daughter. If he's unarmed, he's not a threat to you, but he is a threat to your daughter, so you do what is necessary to eliminate that threat, which may include killing him. Pacifism is as much an emotional response as violence. The intellectual does what is necessary.
