Remember Josef Fritzl? He’s the Austrian man who made headlines earlier this year when it was discovered that he had locked his daughter in a cellar for 24 years and fathered seven children with her, only three of whom he allowed to live upstairs with him. The Telegraph reports that a “highly confidential” report by a forensic psychologist on Fritzl was recently leaked to an Austrian tabloid. “I realized I had an evil side,” Fritzl is quoted as saying in the report. “But I managed to contain myself for quite a long time, for someone who was a born rapist.” Apparently, Fritzl served a prison sentence after raping a nurse in 1967. Later, he came up with what the examining psychiatrist called the “ideal” solution—upstairs he’d lead a normal life, while downstairs he’d act out his dark side, determined to possess his daughter so completely that even if she broke loose, she’d never be attractive to another man.
