My question comes from reading the article on Alternet: http://www.alternet.org/books/145819/ayn_rand,_hugely_popular_author_and_inspiration_to_right-wing_leaders,_was_a_big_admirer_of_serial_killers?page=1
To summarize the article, Rand supposedly idolized the serial killer and used him as inspiration for the leads male characters in her books, notably Howard Roark. Further, Rand is claimed to represent a bastardization of Nietzsche and Schopenhauer, and that through her work she seeks to develop a environment in which sociopaths like Hickman can thrive.
I realize that even if Rand used Hickman as a model, it does not necessarily change the validity of Objectivism as a philosophy. But I am curious as to the extent to which the claims regarding Hickman as an inspiration for Rand are true, outright false, and/or a distortion/misrepresentation of the facts.
