The impending tyranny of Daenerys Targaryen

The question is if Daenerys truly thinks of her crown as something she wears for the good of the people. Of course she keeps talking about making a better world and leaving the world better than how she found it, but it’s always a secondary theme in her stump speech. The primary theme is always “I am the rightful queen of the seven kingdoms” and “kneel or burn”. In her head, she is justified in most of her actions because she was wronged as a child and hunted, sold and abused across the narrow sea for a good part of her life. In many ways, many of her actions were justified, but what happens when the justifications run out and she still needs to rule and act?
