1. Gas Chamber
Someone made the decision to create this device that was used to murder humans at some point in time. In an effort to execute its condemned convicts in a more humane manner, Nevada initiated the use of cyanide gas in 1924, which led to the invention of the gas chamber. The first person to be gassed to death was Gee Jon.
Additionally, during World War II, this was also employed in Germany as the “preferred” means of execution during the Holocaust. This terrible creation, which is only one of many that simply add no benefit to this planet, has no particular advantage.
