Actually, I know what kind of psychopath: the kind who ran the only startup I ever joined. He once told me, "I am at war, and if one of my men can't keep up, I will shoot him." A remarkably similar sentiment to yours! He also used to phone people up and yell at them if they didn't stay till midnight or come in on weekends.
Needless to say (or so I would have hoped), this is an algorithm to produce not a "complex product" but a fiasco, and that is exactly what happened. I was long gone before then, though. What kind of leader shoots his own men? What kind of people want to work for a leader who shoots his own men, or doesn't care if their families die? I know what kind: scared, servile placators. And since such a team hardly makes for startup success, there really isn't an argument here, only a form of hypnosis.
