Compare Beatty with the book people in the novel "Fahrenheit 451."

Part 2:

So comparing both characters, you can see that they are bosses of their “groups”. They both want to change something and make the world better. Both seem to have read books and have a great interest in books. Another similarity is that they both use fire. Both might know of the problems dealing with the society, they live in, but only Granger shows is antipathy against this system.

But there are also strong contrasts between them. The use of fire stands in a strong contrast. While Beatty burns something down, Granger uses fire for positive action, like cooking or warming. Also the living-conditions are completely different. Beatty lives on a high standard of living, in a house in the city, whereas Granger lives in the forest, without a job or a real home.

Also Beatty stands for oppression, killing and a bad society, whereas Granger stands for freedom, equality and peace.

So all in all you can say, that both characters are symbolic opposites of each other with some similar character traits.
