Our last neighbor across the street ran a kitty Auschwitz. He kept bringing home cats for his three young (under 7) daughters. He wanted to teach them responsibility. It was their job to take care of the cats. Of course, they didn't. They never let the cats inside or fed them. The cats slowly starved, until they died or got picked off by neighborhood dogs. We saved four of the cats, but we lost two that were too far gone to help. All are sweet cats. As for teaching the girls responsibility, I know that the girls purposely killed one of the cats by holding hum under the garage door then using the remote to close it on him. He too was a sweet cat. We used to let him stay with us on cold nights.
