Thanks. I'm familiar with Hare but I haven't read his full-length works or seen Fishheads. Most of my knowledge of this comes from researching mass murderers, serial killers and cult leaders as a hobby. I'm not an expert, but I know a bit. I would love to eventually work with the FBI, though. But that's just a little fantasy of mine.
I don't feel compassion for them, either. I mean, it sucks that their brains are warped but I'm more concerned for their (possible) victims. I wouldn't give them the death penalty just for having psychopathy but I do think we should be more vigorous in rooting them out and separating ourselves from them. Maybe in the future we can do genetics testing or brain scans and put them on a list to be monitored and put through treatment. A bit harsh, I know, but I don't know what else could be done. They're the ultimate predators wearing masks of normalcy. They're frightening. Maybe they can teach courses at schools on recognizing the signs of psychopathy to increase awareness.
