An answer to this question will depend on the reader and personal perceptions on the story. For example, while Montag is the protagonist and clearly intended to win the reader's sympathies, he is guilty of many past crimes against property and people, including burning people alive when they refuse to leave their condemned houses. He begins to feel guilt for this, but may be seen as a villain for helping to perpetuate the anti-book policies of the government. Some readers may like Professor Faber better, for his book-hoarding and helping Montag to escape, and some might find the cruel honesty of Chief Beatty refreshing for a designated antagonist. The best way to decide a favorite character is to read the book; because of the many layers in Fahrenheit 451, choosing a favorite character will be, in the end, up for interpretation.
