Theseus really wishes she didn't save these innocent people. Then those innocent "mortals" would have stayed mortals instead of roman cyclopes she would have still been a girl with amnesia with her best friend Nico di Angelo who she had a crush on but is falling for Will and she would have stayed a "mortal" instead if a demigod. Also she wouldn't have read a prophecy that ends in her death. Why did she have to be such a good person?
