There is no acceptable context for killing someone other than immediate self-defence
But you know he’s gonna kill a hundred people next week. Starve ten thousands people to death over the next six months. Start world war 3, and cause the death of millions of people. Those people people have no recourse to self defence, but you could defend them, right now.
I’m aware it’s not immediate self defence, that’s kind of the point of the question. How many people die while you work on that change? Why are ok killing to defend yourself now, but not to defend a hundred people tomorrow?
And you hope they don’t come back with more people and a plan for revenge. Napoleon was sent off on his merry way. His return cost over 50,000 lives.
And what if they won’t let you stop playing with then? Children know bullies, too, and know that you can’t just ignore them.
Because you are unwilling to admit that some people need killing. Not very many, in my opinion. There are usually better options. But killing someone is the only way to be 100% sure that they stop hurting people.
