Answer 1

There are a few reasons. But one important reason is the desire to make death less gruesome (yes, that sounds odd, I know). Take VX gas for example. It causes the nervous system to break down, paralysis, and death by asphyxiation. That’s a pretty bad way to go compared to a bullet to the head or getting blown up.
