>there are STILL people who believe that you can be nice to them and they'll be nice to you, both in and out of universe
I don't believe kindness is the solution but I think it's theoretically possible to coexist with them based on their behavior in the anime, that being said I don't think the world as it was presented has a path towards that theoretical.
So while I think Frieren's belief are wrong about the details of demonic nature her approach is the correct one.
