Five hundred people chosen at random would be a microcosm of the country as a whole, it would reflect the tastes, ambitions, diversity and character of the country, and it would be unable to formulate central plans, the kind that result in millions of executations.
Also, slaughters by mindless mobs are common as dirt in human history. When they're led by intelligent people they just do a better job of it.
