Being "a profit obsessed psycho" might help some people rise to positions of power, but I think the stronger point is that a corporation is an emergent superorganism with its own identity above the individual human level, without a psychology, that operates on its own principles of self preservation based on the incentives of the environment it operates in and that individual choices result in a gestalt of behaviors that no one person really has full control over even though they are part of it and what they do does affect the overall outcome, like a cell and organs making up an animal.
