It's not fiction's job to be photographically representative of reality. If I want to make a fictional world where there's no kindness, this doesn't mean I believe there's no kindness in the real world. In fact, what it may mean is that I very much value kindness. Like if you make a painting in which only greens are allowed, it wouldn't mean you don't believe in blue.
