The motivation isn't revenge. The motivation, at core, is survival. To exist without being hunted, experimented on, eaten. As long as the demons exist and humans have to guard against them, humans will be at a loss. So, while revenge is part of what some want, the key issue is how to live free and not be livestock anymore. In Norman's mind, the eaters of humans must die. (And honestly, how many of us would feel sorry for beings who raise us like chickens or pigs in order to feast on us?)
This kind of reminds of Parasyte.

Tbh, I kind of agree with Emma. Yes, demons kill; some even do it for fun but aren't it hypocritical to eliminate and commit genocide to one race in the defense of avenging the people who died from the same actions they are doing?
It will turn into an endless loop of revenge, each generation rising up and taking the dominant lead in the food chain before getting overthrown by the bottom group.
It's been proven that there are methods and ways that demons can survive without the consumption of humans but due to a corrupt hierarchy, it wasn't possible to do so without getting killed. Imagine if it was actually possible to be a demon without eating human meat to survive, the benefits of demons and humans walking alongside each other without fearing about death. How much mankind and demonkind would grow as a society if we just went along.
People like to view pessimistic ideas as the "reality of the situation" but never think of the possibility of a positive outcome.
