How would you describe Montag's feelings as he burns his own house?

Montag enjoys burning his own home because it means he is destroying all of the emptiness that it represents. He wasn't happy in his home with his wife Mildred. When Montag finds out Mildred was who called the alarm on him, he decides there's no reason to save a home for a broken marriage. The text describes what Montag thinks and feels as he goes from room to room with the flamethrower. First, he goes to the bedroom and burns the twin beds. Their marriage was so divided that he and his wife didn't even sleep together in the same bed. He is actually surprised when the beds burn "in a great simmering whisper, with more heat and passion and light than he would have supposed them to contain" (116). It's as if there is more emotion involved burning down the bedroom than was ever felt therein.

Next, Montag burns the bedroom walls and cosmetics chest before moving into the dining room to torch everything there. As he is torching the dishes, he remembers how empty he felt in this house "with a strange woman who would forget him tomorrow" (116). He is really feeling the futility of their relationship and their life together as he burns everything. As a result, he feels the joy of burning something again. Montag rationalizes his feelings by thinking that since there was no solution to the emptiness he felt in his life, then burning down the house that represented his emptiness is not problematic.

When Montag reaches the dreaded parlor, he takes full pleasure blasting that room with fire. He's more than happy to throw flames on the walls and screens in an effort to destroy the emptiness they always seemed to cause him.

"The emptiness made an even emptier whistle, a senseless scream. . . He cut off its terrible emptiness, drew back, and gave the entire room a gift of one huge bright yellow flower of burning" (117).

Montag really works up a sweat burning his own house. It's as if he is symbolically burning down his old life to replace it with a new one. At the end of it all, it seems as if Montag is relieved, in a way—relieved to have some closure to the unanswerable questions about his life and his marriage. All of those concerns go up in smoke just like his house.
