After almost 2 decades in the industry, working at tens of companies in two continents, I can say without any hesitation that the best managers are never sadistic.
Within the context of a dysfunctional, fear-driven company, these sadistic techniques might squeeze better performance out of certain workers, but a force of creative, thoughtful, talented, self-motivated workers will work elsewhere. While I have worked in a few dysfunctional, fear-driven companies over the years, I did not see any of them grow or hold onto talent over time. The best companies I've worked at terminate abusive managers if they accidentally hire one. They take kindness and empathy very seriously.
