Story about people who have changed through teleportation

Question

I don't remember the storyline, but background info stated that teleportation of people left them changed. They lost their soul or emotions or something. There was a special term that was used for people like that, who were regarded as outcasts. The protagonist (male) is someone who has been teleported himself. He doesn't live on Earth. The story itself is not about teleportation. I read it ages ago, suspect the story is at least 30 years old.

Answer 1

I am thinking of "The Hatchetman" by Fredric Brown and Mack Reynolds, available here.

Duplicated teleported people are called "Duplies"

He knew all too well the character of the Duplies, products of the Duplicator. Their complete egotism, their utter lack of any moral sense whatsoever, their cold viciousness and inhumanity. But he was still amazed that they’d have the utter gall to construct an illegal machine of their own here on Venus

---

When the switch was thrown there’d be a duplicate of him on Mars — except that duplicate would be a Duplie instead of a human being. It would be exactly like him in every way, except that it would lack that intangible ingredient “soul”, that ingredient man had never been too sure he had until the Kingston Duplicator had proved it to him — and had created chaos in the process.
