“There’s no way you can wake up one morning and say, ‘Okay, I’m gonna drug my wife,'” said Darian.
“So I think there are two Dominiques co-existing in him. He decided to choose the dark side.”
She added: “I don’t know if he is a monster, but he perfectly knew what he did, he’s not sick. He did everything consciously.”
Darian herself believes she was drugged and raped by Pelicot, after pictures of her naked and unconscious body were found among the detailed records her father kept of his crimes.
Pelicot denied during the trial that he had ever abused her as the two clashed in the courtroom.
“He’s always lying,” Darian told the BBC.
“I know that he drugged me, probably for sexual abuse, but I don’t have any evidence.”
Darian added that she now sees her father as only “a stranger”.
“I look straight to the criminal, to the sexual criminal he is,” she said.
The release of the interview comes as Darian will narrate a TV documentary on the use of drugs to enable rape and sexual abuse.
Slated for broadcast by France 2 on Jan 21, the 90-minute film is set to include testimony from six other victims raped after being drugged unwittingly.
