Chosen answer: A simple question with a complex answer. When Ed Norton's narrator character mercilessly beats Jared Leto's Angel Face to a pulp in the film, Norton only explains that he "wanted to destroy something beautiful"; in the novel by Chuck Palahniuk, however, he gives a more psychotic reason: "What Tyler says about being the crap and slaves of history, that's how I felt. I wanted to destroy everything beautiful I'd never have. Burn the Amazon rain forests. Pump chlorofluorocarbons straight up to gobble the ozone. Open the dump valves on supertankers and uncap offshore oil wells. I wanted to kill all the fish I couldn't afford to eat, and smother the French beaches I'd never see. I wanted the whole world to hit bottom. Pounding that kid, I really wanted to put a bullet between the eyes of every endangered panda that wouldn't screw to save its species and every whale and dolphin that gave up and ran itself aground. Don't think of it as extinction. Think of it as downsizing. For thousands of years, human beings had screwed up and trashed and crapped on this planet, and now history expected me to clean up after everyone. I have to wash out and flatten my soup cans. And account for every drop of used motor oil. And I have to foot the bill for nuclear waste and buried gasoline tanks and landfilled toxic sludge dumped a generation before I was born. I held the face of Mister Angel like a baby or a football in the crook of my arm and bashed him with my knuckles, bashed him until his teeth broke through his lips. Bashed him with my elbow after that until he fell through my arms into a heap at my feet. Until the skin was pounded thin across his cheekbones and turned black. I wanted to breathe smoke. Birds and deer are a silly luxury, and all the fish should be floating. I wanted to burn the Louvre. I'd do the Elgin Marbles with a sledgehammer and wipe my ass with the Mona Lisa. This is my world, now. This is my world, my world, and those ancient people are dead." - Fight Club by Chuck Palahniuk.

Answer: The simpler answer is: from the Narrator's point of view Tyler appeared to favoring Leto, since the Narrator hadn't come to terms with the split personality yet he obviously felt deep seated jealousy. It says right in the scene beforehand that "I am Jack's inflamed sense of rejection."

Chosen answer: He had been living in a deeply schizophrenic world, living two lives, but not remembering one of them. When he realised that he was actually TWO people, he realised that he could kill them both with one shot. So, his eyes were finally opened to the truth. As it happened, he didn't actually kill himself, but the dark side accepted that he had.
