Some of the animals remembered – or thought they remembered – that the Sixth Commandment decreed “No animal shall kill any other animal.” And though no one cared to mention it in the hearing of the pigs or the dogs, it was felt that the killings which had taken place did not square with this.

George Orwell

Animal Farm. Chapter 8. The animals did not publicly comment on the killings – Napoleon’s dogs were on the prowl to ensure that – but they were not in wholehearted agreement with them.
