What is the climax of the book Fahrenheit 451?

The climax of Fahrenheit 451 by Ray Bradbury would be when Montag murders Beatty. Beatty represents a contradictory society, one that's more of a do-what-I-say-and-not-as-I-do. This is because it is obvious that Beatty has a vast knowledge of various books, despite being a fireman Captain.
