Final answer:
Guy Montag, the protagonist of 'Fahrenheit 451,' is a firefighter responsible for burning books in a dystopian society. He begins to question his job and societal values throughout the story.
Step-by-step explanation:
Guy Montag is the protagonist of Ray Bradbury's novel Fahrenheit 451. His profession is a firefighter, which, in the dystopian society of the story, means that he is responsible for burning books, as they are illegal and considered dangerous to the societal order. Montag starts the novel fully engaged and seemingly content with his job and the society in which he lives. However, as the story progresses, he begins to question the very foundations of his society's values and his own role within it. This inner turmoil and his growing doubts about book-burning bring him into conflict with his role as a fireman.
