It is also important to note that major offenses within the fight club are punished through castration, as if to imply that the punished person is no longer a man and therefore no longer worthy of being part of the violent organization. The roles of women in Fight Club are extremely limited. Marla Singer is the only female character in the film. She shares qualities that are present in "Durden," yet the narrator is unable to recognize the relationship that he and Singer develop due to his preoccupation with "Durden." Much like the narrator, Singer is nihilistic and attends support group meetings in order to feel complete. Furthermore, the only relationship that she develops with "Durden" is one that is strictly sexual; "Durden" has gone as far as instructing the narrator to not talk about him to Singer. As the narrative of the film progresses, and "Durden" gains power over the narrator, Singer is seen as a threat to their existence and their dream of destroying corporate America. Due to the danger that Singer poses, it is determined that she must be destroyed, although she becomes the narrator's sole companion at the end of the film after he "kills" "Durden."

One of the main goals of the fight club culture, once it has further evolved into a covert criminal organization, is the destruction of consumer-supported...

Criminal deviance is motivated by the organization's desire to disrupt society's need to consume, as well as, create chaos within the organizations that enable mindless and unnecessary consumption of goods. The corrupting nature of the fight club also infiltrates the service industry, specifically law enforcement and the food-service industries, including bars and restaurants. The ability to recruit other men with similar ideals and social frustrations facilitates the expansion and proliferation of the fight club, both as a male support group and as a criminal organization. The fight club does not seek to injure or kill people, rather seeks to punish the organizations that entice consumers.
Fight Club is a commentary on capitalism and consumerism. The film satirizes the dangers posed by capitalism and consumerism on the individual and proposes a ridiculous solution to the eradication, or at best, disturbance of consumer behaviors. The fight club's ability to infiltrate all aspects of an ordered masculine society allows the audience to see the dangers that are posed, and though they may not actually occur, provide insight into how consumers have been blinded by advertising and how they mindlessly indulge consumer-supported conglomerates.
