But generally, when these sorts of things come up in novels or movies, the expected answer is "you are thinking too much about this, just focus on enjoying the story the author is telling". The problem with this as a DnD experience is that we are the authors, even as players. And this sense that we are incorrectly "thinking too deeply" about the setting, the goals, the motivations, and the consequences of the world... is a little jarring for me. We should encourage deeper thought, I would expect, not treat this the same way we treat more passive media.
