I guess the issue is that it’s sort of like giving a history of the USSR and just stopping in like, the seventies. The Morlocks are definitely monstrous (as where the early Eloi and the humans who evolved into them), but part of the idea of the book is that that monsteresqeness will eventually rob the entire species of its very sapience. It’s hard to talk about the USSR as a state if you don’t talk about how that state collapsed, and the Morlocks are a similar thing.
