I wonder if murderers, on the whole, are not particularly fearful people. Like, has there been a comprehensive study of the personalities of murderers? I would think they probably aren’t ruled by fear – because fear would surely prevent them from doing something as risky as murder. Like, a fearful person may really want to murder his brother but he’d be afraid of being caught, or going to hell, or failing at it, or or or. Maybe murderers are an odd kind of optimist – the kind that assumes their actions will have no unwanted consequences.
