A dictatorship is a form of government characterized by the absolute rule of one person or a very small group of people who hold all political power. While a dictatorship is a form of government in some nations, just as monarchy or representative democracy is the form of government in others, dictatorships are seen by non-dictatorships as dangerous and cruel because of the way they tend to treat their citizens. A dictatorship is often characterized by harsh treatment of citizens, and violation of rights. The absolute control of power that they possess, is extremely dangerous, and for society to flourish, power cannot be absolute. However if the dictatorship is a good one, it can lead to progress of the economy, and a reduction in crime rates. Assuming the given information is true, pick out the most appropriate option.
