Rodger left a lengthy manifesto describing what he hoped to do, and outlining his hatred of women. According to the New York Daily News:
In the repulsive manifesto he penned before killing six people and himself in seaside Southern California, tortured Santa Barbara college student Elliot Rodger vowed to “punish all females for the crime of depriving me of sex.”
“They have starved me of sex for my entire youth, and gave that pleasure to other men,” the sex-obsessed 22-year-old virgin wrote in his 137-page screed, titled “My Twisted World.”
“I cannot kill every single female on earth, but I can deliver a devastating blow that will shake all of them to the core of their wicked hearts.”
“Females truly have something mentally wrong with them,” Rodger wrote in the rambling diatribe, which he emailed to two dozen people ahead of his bloody Friday night rampage.(See also these New York Times and National Post articles). Rodger planned on killing his roommates (he stabbed both of them to death, plus another male visitor), then drive around "splattering" as many people as he could with his car and shooting others.
What I wonder is where did he get the idea that the measure of success was casual sexual encounters, or that common people were inferior to him and existed only for his amusement and pleasure? Was it perhaps the liberal-progressive culture from which he had imbibed his whole life?
Update: Where did Rodger learn to objectify women? The Daily Mail reports that his father, Peter Rodger, sells erotic photographs (NSFW).
