I don't think a manager in most companies should strive to be feared, at least not for the people under them (maybe when trying to get things for their employees, like raises or need another team to get off their asses and get shit done that they need). The most I've ever wanted to leave any company was when I was under a manager that made sure they were 'feared' more than loved amongst the people under them. And especially in tech, the best employees (who can do a mean Leetcode, at least) won't stick around for that shit. It's too easy for them to go elsewhere. For monarchies I imagine that would be different.
