That is the problem, they are not going to change, the spider makes it clear, they are monsters and it is in their nature, even in her bond stories she makes it very clear, and yes, the gods and others, but that is already going to the extreme to justify the masochism of the creator to make us look bad every time we create a genocidal route, but it doesn't work, at least it didn't convince me.why should genocide route be the best for kazuya? I dont think its morally correct to curse someone for all eternity with a disgusting blob god that only wans to kill / consume. If there was a way to kill and exterminate the demons without kazuya suffering? Then it would be 100% okay and you actually save a lot of human lives in the long run.
And I only played it because of the MGQ Paradox crossover.
For the simple fact that I have to make friends with monsters like the spider or the parasitic bird (it already has a lot since I played, so I have lost my memory, and look, it means that I am not very interested in the game), that world is already lost.
