Answer:
It has been historically proven time and again that former authoritarian states or repressive governments cannot just be a democracy. Becoming a democracy is a process that could take years and lots of casualties. Take for example the US. The colonial US was under a monarch which w could say was our repressive government. It took the colonial US decades to get out from under the thumb of British rule, two wars, and a failed government to become a democracy. And even at this moment that democracy is falling apart. So no, a country cannot just be a democracy unless that country goes through the process of removing/eradicating bad leadership, recreating its government, and instituting and maintaining a somewhat fair political system.
