I confess. It did take me a full year to understand why the farmer - beef raiser near me kept a donkey or two out with the cows.
You nailed it. A donkey is about the smartest, meanest, nastiest creature on the face of the earth and the Bible even asks if man is up to taming the wild ones. Ought to tell people something, but they don’t get it until they see a Coyote (number 2 on the list of smartest, meanest, nastiest) after it’s been torn up by a donkey.
