Women who fall in love with killers have always fascinated and repulsed me. What drives them? Do they think they can ‘save’ these men? Are they secret sadists, acting by proxy? Are they masochists, getting a cheap thrill from communicating with someone who has tortured a fellow woman to death? Bonnie and Clyde syndrome, also known as hybristophilia, puts the case that, as an evolutionary reproductive trait, some women can be drawn to ‘bad boys’ who are prepared to break rules/laws and are therefore ‘stronger’.
