^Dany rode close beside him. "Still," she said, "the common people are waiting for him. Magister Illyrio says they are sewing dragon banners and praying for Viserys to return from across the narrow sea to free them."
"The common people pray for rain, healthy children, and a summer that never ends," Ser Jorah told her. "It is no matter to them if the high lords play their game of thrones, so long as they are left in peace." He gave a shrug. "They never are."
Dany rode along quietly for a time, working his words like a puzzle box. It went against everything that Viserys had ever told her to think that the people could care so little whether a true king or a usurper reigned over them. Yet the more she thought on Jorah's words, the more they rang of truth.^
This is from Daenerys’ third chapter in the books series - so very early on. She had bought into her brother’s fantasies that the seven kingdoms were desperate for the return of the dragons all her life. There are flashes of moments in the books (such as this one) where she questions whether this is truly her ‘destiny’ but she stubbornly holds onto this idea throughout the series.
It’s a great tragedy, really. She built up a huge following in Essos based on what she had achieved to the extent that she reached god-like status, but she’s going to chuck it all away on this abstract notion of her divine destiny to sit the iron throne.
She made a comment that her destiny was to overthrow tyranny whatever the cost. The cost will be her becoming a tyrant.
A young, inexperienced ruler with natural human failings should never have that much raw power of destruction at their disposal. Yes, it can be used to destroy ‘evil’, but at what cost?
