Scripture permits self-defense and defense of innocent others; military service can be just, but soldiers retain moral responsibility to refuse unjust orders.

Mike argues Scripture supports self-defense and places a positive obligation on believers to protect innocent people around them. He uses a home-invasion scenario: if a family member's life is threatened, shooting the attacker is morally appropriate and good. On military service, Mike applies just war reasoning: violence in defense of the innocent and against true oppression can be righteous. However, soldiers cannot simply follow orders as moral cover (invoking the Nuremberg defense/Nazi example). He rejects "I can kill anyone my country tells me to" and affirms the existence of just wars while acknowledging unjust acts occur even within just wars.
