What role do your values, beliefs and experiences have in how you analyse and interpret works of art? When you think about whether you are sympathetic to a character or not, do you think that you are you influenced by your culture? Reader Response theory would be a great lens through which to reflect on your own values and beliefs as you approach this violent and taboo-busting tragedy.

Why not connect this literary work to Euripides great play, Medea. The theme of violence is a clear connection, but you could also explore the representation of women within a patriarchal society, as well as explore the concept of rebellion.

I can imagine reading a fantastic Paper 2 response which addresses this literary work. You would need to think about which other literary work to compare it to: power structures in Medea? Language and violence in Margaret Atwood? Systemic oppression in Citizen? There are so many possible avenues to explore which would allow for interesting analysis. See this page for some ideas on how to get started.
