Failure to introduce democracy is not the same thing as failure of democracy. Just like a failure to implement encryption doesn't mean that encryption is a failed concept. Can you provide example of democracy brutal to minority? Which actually allows the minority to vote as well? That could be prevented if only political elite of the time would have say in the matter, then it wouldn't have happened? I don't think there is a historical example.
