The benefit of a dictator taking over a democratic government is that it will, in time, shake the apathy from people over the rule of their government.
Is the apathy goes, the voice of the people will be heard and change can begin in either replacing the dictator or cause the dictator to begin to treat the people as having a meaning and purpose.
Dictators do not see constituents as having a useful role in the operation of government, they just see them as a group to do as the dictator bids.
Hence, apathy is the enemy of democracy and the appearance of a dictator will cause a reduction or loss of apathy
