“Is it true these people really don’t have a conscience?”
Read the book “Without Conscience” by Dr Robert Hare. He’s studied psychopaths in detail. He also co-authored “Snakes In Suits”.
Fourteen percent of the population have limited or no conscience which, among other personality characteristics, qualifies them as psychopaths. The good news is only a small percentage of that 14% are killers.
I personally knew one such person, a female co-worker and she actually threatened to kill me but never went beyond the threat.
When this girl acted out she had absolutely no remorse. All of her problems were someone else’s fault. She was very charming. Her life’s goal was to bed every guy she knew, in particular cops. I would not fall for it, which had her plotting against me and using her powers to persuade the cops I was a bad guy.
Read “ Bad seed from Rosebud”.
If you have a brain or a soul it will convince you that the death penalty is needed and WAY underused!
