The subjective nature of evil

Damien, my identical twin brother, may be visiting me in a few weeks, which is very cool as I haven’t seen him for nine months.

He lives in a renovated silo penthouse in inner-city Sydney, drives a 2004 Mini Cooper S (yellow with black racing stripes), and is a senior executive at Coca-Cola Amatil.

I write and edit horror stories.

Which of us is the evil twin?
