The noose was made for monsters like Ian Brady and Myra Hindley. But the UK (like most of the West) is oh too civilized to go for that. It was much easier to pretend, and give them prison sentences instead.
In a way, it’s like having a wolf in your sights, but letting him go. You are then oh so humane. No matter that the wolf has tore the guts out of many sheep.
My dream job is executing people like this. I’d want to do it my way. It would take a while.
