they would have realize that the the murder be all in his head . he be an american psycho . a fraud . a tacky and tacky fraud and a most people be in the 80 . a be the purpose of this book . to comment on the american condition during that time ( and in my opinion it be still mostly apt ) thus negate the premise of this entire movie . unless your an idiot and completely miss the point of either the book or the movie . then the movie will still suck . i still can not believe when business in america count on american stupidity . they win . because it true . how could anybody misinterpret such a concise end . how exactly do you fee a kitten to an atm anyway . arrrrgghhhh . read a book . ( note imdb would not let me format this comment a i wish so imagine this all in cap and i be shout in outrage ) .
