* Complex and Multifaceted: Faber is not simply a wise old man. He's a complex individual with a rich history, a deep understanding of the society's flaws, and a strong moral compass. He's driven by a desire to preserve knowledge and fight for freedom.
* Internal Conflict: Faber grapples with his own fear and inaction. He regrets not taking a more active role in fighting against the system earlier. This internal conflict makes him relatable and adds depth to his character.
* Growth and Change: Throughout the novel, Faber evolves. He goes from being a passive observer to actively aiding Montag in his quest for truth and change. His willingness to step outside his comfort zone and take risks demonstrates his growth.
* Motivation: His actions are driven by a mix of motivations – his love for books, his desire for knowledge, and his commitment to human connection. This makes him more than just a plot device; he's a nuanced character with believable desires.
* Relationships: His relationships with Montag and Clarisse influence his actions and reveal different aspects of his personality. He's supportive, insightful, and ultimately a catalyst for change.
In contrast, a flat character would be simpler, with fewer dimensions and limited development. Faber, with his complexity, internal struggles, and dynamic nature, clearly fits the definition of a round character.
