Characters
I never made a conscious decision to have the club become one thing or another. It just happened before my eyes. Each savage event was a catalyst for the next. And by the time the violence reached epic proportion, I couldn’t see it. Blood was every color.

Our reading
An editorial interpretation.
The speaker says the club changed without a conscious plan, with each savage event setting off another. They describe becoming unable to recognise the scale of the violence. The final image of blood in every colour suggests distorted perception, while the account leaves their own responsibility open to scrutiny.
