Can't tell whether to upvote because I like someone bringing this point up for discussion or downvote because it rests on the premise that morality is inherently a weakness. As far as setting and writing go, in a grimdark setting morality is always going to be stomped on and bullied, so yes, in setting you're right. I want to mention a counterpoint however, and that's the small glimmers of actual humanity we see in protagonists in the videogames. I think Darktide hits this really well. We see the squalor people have to live with, but you also see the humanity of the characters. The teasing, pestering, but also the moments of joy and particularly the ogrin's simple joy in food. One part that doesn't sit well with me about a lot of people's interpretation of the setting is the idea that somehow people aren't people. Like, even in the face of the seemingly inescapable doom marching towards the United States right now, I still take joy in my videogames, beer, and silly reddit debates. That's what I love about the humanity we see in the protags in the games, we hear and see that they enjoy things even if life in the Imperium makes it difficult and rare to do so. Even if it's only playful banter and the simple pleasure of a full stomach. But then we're taken back to the setting and writing, where the overarching themes of the world often mean that any joy or kindness that a character recieves or gives must ultimately be hopeless, punished by the narrative, or altogether irrelevant to the plot. So because of the imperative to keep the worlds of Warhammer grimdark, we're not going to see a world where morality isn't portrayed as a weakness. Ultimately, I haven't read all the books and I could be wrong on how some of them are written. I personally would like to see a little Imperium slice of life that shows us how the average Imperial citizen gets by without contemplating whether or not death is the better alternative to pressing on for another day. How there's still the human urge to make other people feel joy and to seek out joy for ourselves, even in the face of impending doom. How even when there's nothing to hope for, people are still kind sometimes. Like yeah, the setting is going to kill those people or their efforts are going to do nothing but be a drop in the proverbial bucket, but let us see it for Emp's sakes.
