Maybe she did. Serial killers seem to attract women just because they are murderers.
I think when it comes to Men, about 40% of Women have a “stupid” gene.
I read somewhere that some sick women like to believe that they are special so that they alone can tame the ‘murderous animal’. They imagine their pet freak is dangerous to everyone but them (like fay wray - King Kong) and they don’t really want their ‘powerful’ freak to get out of jail - they don’t want domestic bliss etc.
