Should there be a ‘John Wick’ defense for murder?

So… killing people.

Justice systems and juries agree there are situations where killing someone else is justified. When your life is threatened by them, most people feel reacting with lethal force is justified. When your family members lives are threatened, most people feel reacting with lethal force is justified.

Some American states have codified this legal principle with “Stand your Ground” and/or “Castle Doctrines” to confirm to their citizens: you have a right to fight back, and kill, in certain situations.

So… my question. What if the situation is “Someone is trying to kill my dog”?

Is retaliating with lethal force justified in protecting your beloved dog?

Would you do so yourself? Would you accept that defense if you were on a jury?
