No, I have not "made a decision". I have analyzed the circumstances and have determined that such a thing is the only decision that is sane. But not in the situation you have detailed. You have instead have detailed a different situation with your example assuming that I have just decided to militarize societies without any outside threat involved, which is a different case altogether, because I wouldn't do that.
I don't get what it, are you saying that a boxer should somehow be expected to solve cancer?To clarify, it seems like you are saying that the campaign world can only include darker elements that were put there specifically for the PCs to solve? Is that correct?
So like, if I am running a game about boxers in the real world, are you saying that it would be unfair to mention that one of their fellow boxers got cancer and retired because you can't simply punch out cancer, and therefore cancer is only appropriate in a hospital drama game where someone is playing an oncologist?
