lmao yes, exactly. anne carson, "The act of severing and tossing away the victim’s head enables him to throw away the anger of all his bereavements." she sums it up perfectly. shauna is a much a tragic heroine as any that euripides wrote about. why does elektra murder her mother? or clytemnestra her husband? why does achilles cut down hector? or medea kill her children? hate and vengence is just something that fills the space love has left empty. you cant often be driven to acts as extreme as these without having lost what you loved the most, aka a parent, a child, a best friend, or a lover, and shaunas lost all of these.
her rage isnt hard to understand. in the wilderness, she lost everything, even herself. was forced to do something unspeakable, and wasnt given the space to grieve, so she lashed out. then she finds a new life, she marries, she has a daughter. 25 years she goes without letting herself be that person again, but now she feels threatened. her family is threatened. shes hunted by her friends, watches nat die, and someone puts the necklace that was placed on human sacrifices around her daughters neck. even if thats not what lottie meant by it, is it any wonder shaunas regressed into a place of violence and cruelty in the face of it.
