@Hilmaam in a democratic system there is going to be very corrupt governments, but they all have end dates, and the more corrupt they are the more the pendulum will swing to the other side in future governments. Which means future governments could be more accountable and less corrupt. All of them having end dates is what really matters, not the voting in or the type of votes processes.
This is not the case in a dictatorship as it has no end date, regardless if its utopian or corrupt, it will end up with an explosion.
So a dictatorship is always bad.'
Take turkey for example, the military sometimes step in and unseats a government, but their military rule has an end date. Even though they are not elected they run the country. The Kacaan did not have an end date.
