To me it seems quite reasonable that the people hired

to work on a bomb intended to kill 150,000 people in one go

against the backdrop of a war where 70-85 million died

might not place the greatest value on health and safety, and the sanctity of human life.

On other human lives. They'd probably damn well care about their lives; otherwise, they wouldn't even make an effort to create "better weapons".
