Destruction gone wild!

The film, Fight Club, is full of incidences where the main characters (Norton & Durden) cross legal, moral and social boundaries. Just one of these cases is when Norton & Durden break into a liposuction clinic at night to steal discarded human body fat since it "makes the best soap." Actually, they don't break into the building, just the property, to access the dumpsters with the bags of human fat in them. They take the bags of fat back to the house to render it & use it to make the soap, which they sell to the upscale stores where women pay big bucks to buy soap made with their own fat.

The above incident is an example of crossing legal (breaking & entering private property), moral (stealing human body fat), and social boundaries (using it with the intent to make soap & sell it back to the same women who frequented the clinic). The characters were using the 'waste' for their own profit to fund even more illegal behaviors of vandalism and destruction throughout the city. I would say they justified this particular method of soap making because the waste came from women who were 'indulging' themselves in a society rampant with excesses. One of the messages being sent throughout the film was how unnessessary and wrong is the general accumulation of material goods, working at a job just to accumulate more 'things' or status, and is something to be 'rejected' and 'battled' - not only on a personal level, but as a society in general. The evidence for this is seen several places in the film. For example, Norton's addiction to Ikea products caused his alter-ego to bomb his apartment to rid himself of material things which were consuming his existence - even to the point of working at a job he hated just to support his material addiction.
