dailymail: Elliot Rodger was trying to act out the role of a film star when he went on his killing spree – to make up for the fact he felt like a failure in real life. Clearly he did not feel he had the status he deserved.
In his last YouTube video, which he explicitly filmed to leave a legacy, he casts himself as a movie star.
In another of his clips he appears to reference the film American Psycho, and it might be that he has taken the main character, Patrick Bateman, as a role model.
