What do you think Orwell shows about two of the following in the text?

Old Benjamin, an elderly donkey, is one of Orwell's most mysterious and intriguing characters on Animal Farm. He is described as rather unchanged since the rebellion. He still does his work the same way, never becoming too exited or too disappointed about anything that has passed. Benjamin explains, "Donkeys live a long time. None of you has ever seen a dead donkey." Although there is no clear metaphoric relationship between Benjamin and Orwell's analysis of communism, it makes sense that during any rebellion there or those who never totally embrace the revolution those so sceptical they no longer look to their leaders for help. Benjamin symbolizes the older generation, the critics of any new rebellion. Really this old donkey is the only animal who seems as though he couldn't care less about Napoleon and Animal Farm. It's almost as if he can see into the future, knowing that the revolt is only a temporary change, and will flop in the end. Benjamin is the only animal who doesn't seem to have expected anything positive from the revolution. He almost seems on a whole different maturity lever compared to the other animals. He is not tricked by Squealer's propaganda like the others. The only time he seems to care about the others at all is when Boxer is carried off in the glue truck. It's almost as if the old donkey finally comes out of his shell when he tries to warn the others of Boxer's fate. And the animals do try to rescue Boxer, but it's too late. Benjamin seems to be finally confronting Napoleon and revealing his knowledge of the pigs' pretence, although before he had been completely independent. After the animals have forgotten Jones and their past lives, Benjamin still remembers everything. Orwell states, "Only old Benjamin professed to remember every detail of his long life and to know that things never had been, nor ever could be much better or much worse hunger, hardship, and disappointment being, so he said, the unalterable law of life."

Orwell uses the dogs to represent the bodyguards of Stalin. The dogs are the defenders of Napoleon and the pigs, and although they don't speak, they are definitely a force the other animals have to abide with. Orwell uses the dogs as a fear tactic to force the animals into believing anything that Squealer or Napoleon says: manipulation comes on to the scene yet again. This argument is supported as Orwell describes Napoleon's early and suspicious removal of six puppies from their mother. The reader is left in the dark for a while, but later it is made clear when Orwell describes the chase of Snowball. Napoleon uses his "secret dogs" for the first time here; before Snowball has a chance to stand up and give a counter-argument to Napoleon's disapproval of the windmill, the dogs viciously attack the pig, forcing him to flee, never to return again. Orwell narrates, "Silent and terrified, the animals crept back into the barn. In a moment the dogs came bounding back. At first no one had been able to imagine where these creatures came from, but the problem was soon solved: they were the puppies whom Napoleon had taken away from their mothers and reared privately. It was noticed that they wagged their tails to him in the same way as the other dogs had been used to do to Mr. Jones." The use of the dogs begins the evil use of force, which helps Napoleon maintain power. Later, the dogs do even more horrible things when they are instructed to kill the animals labelled "disloyal." Stalin, too, had his own special force of "helpers". Really there are followers loyal to any politician or government leader, but Stalin in particular needed a special police force to eliminate his opponents. This is how Trotsky was killed.

Orwell uses fable to show that the perfect society can never be achieved: there will always be workers and leaders, because of the faults in human nature.
