If that truly is the case then they need to be placed away from society for ever.
keep them in comfortable surroundings, access to education etc but they should never be able to walk among us because one day, it could be your child, or your mum, or your husband or your dog, killed by one of them because they simply don't know right from wrong.
The price of keeping people among us who would knife you as soon as look at you because they can't tell right from wrong is a price that is way too high.
Personally, I think the number of people who don't know right from wrong is vanishingly small and that most people would soon know the difference if they were punished and punished hard the first time that they stepped out of line as a seven year old.
However, when every naughtiness is treated with 'love bombing' or a bewildered reading of The Explosive Child then we can simply look forward to young men-and it is mostly though not always-young men- with explosive tempers or paranoia calling the shots for the rest of us.
I can't see it changing unless there is a very unlikely sea change coming when children are disciplined by parents, schools, the police and the courts. When a group of thugs painting graffiti on a park bench run away when they see an adult approaching instead of, as now, fearlessly standing their ground.
