I would say the goal is to make murder look more tidier to the average fool.
I remember back in the mid ‘60’s checking out one of the places near Frankfurt they took handicapped children. It was like a gingerbread house from all appearance, a delightful place to see. I understood in the pre-war days kids were wheeled in and were never seen again. Tidy. Death dealers these days have tidy gingerbread words. Progress, it was, in their way of thinking.
