She sometimes felt she had been cursed, as if by some malevolent goddess in a Greek myth, to lose everyone she ever loved. - Alex Michaelides

A long time ago, psychopathy used to be called simply ‘evil’. People who were evil – who took a delight in hurting or killing others – were written about ever since Medea took an axe to her children, and probably long before that. The word ‘psychopath’ was coined by a German psychiatrist in 1888 […] from the German word psychopastiche, literally meaning ‘suffering soul’. For Mariana this was the clue – the suffering – the sense that these monsters were also in pain. […] Psychopathy or sadism never appeared from nowhere. It was not a virus, infecting someone out of the blue. It had a long prehistory in childhood. […] Yet many children grow up in terribly abusive environments – and they don’t end up as murderers. Why? Well, as Mariana’s old supervisor used to say, ‘It doesn’t take much to save a childhood.’ A little kindness, some understanding or validation: someone to recognise and acknowledge a child’s reality – and save his sanity.

There was a word for this moment in Greek tragedy: anagnorisis—recognition—the moment the hero finally sees the truth and understands his fate—and how it’s always been there, the whole time, in front of him. Mariana used to wonder what that moment felt like. Now she knew.
