I disagree with that assessment. He believes that his take is correct, and it is unnatural for him to admit error, learn the lesson, and move along.
Instead of "stupid", I think that the words 'stubborn' and 'persistent' are more accurate.
Stubbornness and persistence are personality traits that have allowed for mankind's greatest achievements and discoveries. And also our most horrific blunders and disasters.
As such, I hereby nominate the Honey Badger as Bacha's spirit animal.
