My own view is that violence is a part of classical Haida literature - and of every mythology everywhere, so far as I can tell - because it's part of life itself. In the world of the hamburger stand and the supermarket, or the vegan café and the ashram, you might try to tell yourself it's possible to be nonviolent. In a hunting and gathering society, violence is more difficult to hide.
The first function of violence in Native American literatures is simply to acknowledge that violence is implicit, like gravity and sunlight, in the world and our relations with the world.
In the native literatures of North America there aren't any novels. Instead, the major genre is myth. And myths are stories that are fundamentally about the world, not about human individuals. A myth needn't include any humans at all. If it does include them, they're usually minor characters - imaginary humans sent out like scouts to report back on what's happening in the mythworld, but not central participants in the action.
Russian literature, like colonial Canadian literature, comes with a lot of landscape backdrop.
