why did no one care to mention recalling a commandment about animals killing other animals in the hearing of the pigs or the dogs? what does this say about the workers state of mind?

The animals are quickly programmed to say whatever Squealer tells them to say. If they do not follow the "party line," they run the risk of being killed or punished by the dogs. The workers have quit thinking for themselves.
