Explanation:
The author Ray Bradbury showcases Montag as a protagonist character who is troubled with the world around him. He feels he has a responsibility to change how people behave in society, such as facilitating a love for nature among them.
For example, we recall his encounter with Clarisse McClellan, a young woman he met in his neighborhood whose views about nature greatly influenced him, compelling him to be more conscious of nature, wanting to change society.
His troubled emotional state is made evident even further as we observe how he struggles to understand himself, his motivations for doing things which even led him to kill Beatty.
