Why did the Nazis use zyklon-b?

Answer 1

To kill the undesirables they started using bullets but Himmler felt sick after attending a mass killing by guns then they moved to using the carbon M from trucks even that was to slow Zyklon-B (A juwish invention) was found to be fast and cheap.

Correction:

Zyklon B was originally devised as a pesticide sometime in the 1800's. It's primary active ingredient is hydrogen cyanide, a hugely lethal cytotoxin. The original discoverer of this compound has not been sought nor identified, but as cyanide has been used in dyes from dawn of time, predating Judaism, we can safely assume it was not invented by a "juw"[sic].

The choice to use of Zyklon-B was certainly economic. There are huge logistical and cost related problems involved with killing 6,000,000+ people, and the cost of ammo as the means of homicide is prohibitive. Pesticide presented an economical alternative.
