Well said. To be clear, I agree with your outlook on human nature, but I try to check myself on not being optimistic to the point of ignoring people’s history. People do change, but we can’t presume in which direction that will be. We must remember improvement is a hope and a genuine possibility, but not an expectation. On the other hand, Orwell is regarded as insightful for good reason but of course he is also very cynical about people and the future.

A catspaw is just a term for someone who is used as a tool of another to their detriment. It comes from a French fable where a monkey convinces a cat to grab some roasting chestnuts for them to eat, but the monkey eats them all while the cat ends up burning its paw.

Edit: This is the fable. https://en.wikipedia.org/wiki/The_Monkey_and_the_Cat
