Despite mounting criticism, an animal shelter in some obscure Texas city announced that it will continue to kill animals with lethal gas and not lethal injections because the employees find it less stressful—a sentiment likely shared by Nazi death camp workers. An official argues the merits of gassing vs injections:

“You have an option of a method, carbon monoxide, that is simply more efficient and causes less emotional stress on employees,” he said, emphasizing that every precaution is also taken to prevent employee exposure to the gas. “We put our employees first.”

Basically, flipping a switch to kill something is much easier than stabbing it. |DallasNews|
