What is boxers from animal farm fatal flaw?

Boxer's fatal flaw in "Animal Farm" is his unwavering trust in the leadership and his blind dedication to hard work. He believes that hard labor and loyalty will ultimately lead to a better future for all animals, which causes him to ignore the signs of corruption and betrayal from the pigs. This loyalty ultimately leads to his tragic fate, as he is exploited and sold to a glue factory when he can no longer work, highlighting the dangers of misplaced trust and the exploitation of the working class.
