"But I no longer feel so completely confident about the line that divides ‘abusive people’ from ‘the rest of us’."

"Rooney says it didn’t interest her to put the violence centre stage. 'I used to believe that abusers (and in particular, men who abuse women) were boring. And I still think there’s some truth in that, and I still find our cultural fixation with men who rape and murder women very tiring. But I no longer feel so completely confident about the line that divides ‘abusive people’ from ‘the rest of us’. And the novel maybe interrogates that division at times. I am probably never going to write a book from the perspective of a serial killer, but I do believe that many decent people have done things they now consider deeply wrong.”

~ Emma Brockes, Sally Rooney
