FUN FACT: Ayn Rand’s original protagonists for her novels (whom her later protagonists were based off of) were based on a psychopath named William Hickman that kidnapped a little girl, demanded ransom, received it, and mutilated her body anyway, returning to her parents a corpse without internal organs.
To be fair, she wasn’t admiring this monster’s horrible acts (what she called his degeneracy). But it seems like she was inspired by how Hickman couldn’t be controlled by the imposing and controlling morality of society. She wanted “A Hickman with a purpose” in Renahan, her protagonist.
“The first thing that impresses me about the case is the ferocious rage of a whole society against one man. No matter what the man did, there is always something loathsome in the ‘virtuous’ indignation and mass-hatred of the ‘majority.’… It is repulsive to see all these beings with worse sins and crimes in their own lives, virtuously condemning a criminal…”
According to the Wikipedia page, Rand liked how Renahan was
“born with a wonderful, free, light consciousness — [resulting from] the absolute lack of social instinct or herd feeling. He does not understand, because he has no organ for understanding, the necessity, meaning, or importance of other people … Other people do not exist for him and he does not understand why they should.”
