I have never liked that kind of thing since I was a child... Dolls were originally used as funeral objects, used to replace people, and they became dolls for people, but what exactly is a doll? With an anthropomorphic appearance, it would be more accurate to call it a plaything than a playmate, but it is given a human-like appearance... It is really difficult to understand why it is said that it is a toy with emotions. However, if they really have something like a soul, wouldn't it be like hell for them? The random thoughts come from the author's phobia of humanoids. Don't take it too seriously. It's not a very interesting story.
(Lily is probably because the characters are all from a young female perspective. The explanation of mutual attack here is similar to doting on each other (laughs)...)
