Is Dany fit to be queen ?

Well, we are down to one more episode next week and now after this last episode where Dany went full on revenge and burned the city and killed innocent people, while Jon watched and now the question is will Dany really be Queen just because she won the war?..
I read a lot of some of other posts about Dany; some still defending her rage of fire, some calling her the mad queen?. But I think Dany's story is in the GOT is actually a cautionary tale that even in eight season people are still are not getting. This is not about good versus evil; where the Dany is suppose to be the savior.

I think Dany's quest for power was written to put the question to us to think, just because she is of royal blood; just because she has been resourceful, determined, gained armies and allies or that she really believes she will be a good ruler; does all this mean she should become the queen? Dany exemplifies a person whose hunger for power gradually consumed her, it created fear in her; fear for someone who is never had real power is also very dangerous thing. Fear can mutate to blind suspicion, anger and hate. Dany's decision to killed Varys was because he spoke the truth of Dany really is not fit to be the queen, Dany would even kill Sansa if she could or anyone else she is a threat?. She is not mad, she was just a spoiled brat that got consumed by power, because she never had it before. She never leaned its meaning, she never grew up with her family to learn and understand what it means to be a ruler, otherwise she would not let her emotions and hatred of Cersi to burn an entire city and kill women and children; knowing full well that her father was the mad king that almost did the same. From the time Dany set on that quest of the thrown, she had a self-entitlement attitude that she is the rightful heir and the her people are waiting for her; then she burns her people without mercy; people who she came to rescue. After all her struggles and accomplishments she never really understood the real meaning of what it really means being a leader; a good leader is tempered and measured as Vary said that about "jon", but Jon grew up and learned from a leader of the north "Ned Stark", to be a leader it also means you are responsible to the people who you are going to rule, Dany has never really understood that, all she pisses and moans about that she is the right heir to the Iron throne, its like a mantra for the entire show.

I personally never liked Dany's character in the entire show because I saw the signs of her misplaced expectations very early; to me they were the red flags that most people dismissed. Even after last night's episode; after Dany destroyed an entire city and killed people, I saw people still posting comments on GOT boards defending her action of rage that it was justified?
this is why I think most people still don't get this story's theme or meaning.

So, If you have watched the entire show from the beginning like me; you also know that GOT is not as predictable as we want it to be. I personally don't think Dany will end up on the thrown; I don't think it will be Jon either, even though we all want him to be, but I tend to focus more on the character itself and I think Jon's heart is to be in the north with his family. I have never read RR Martin books, but just watching this show; I think he had a purpose to convey a message about power, the use of power, and what it takes to get it, that's why he called it game of thrones. He said in one of his interviews he based a lot of this story on historical events like "War of the roses" and how power shifted from person to another and at what cost. I think the ending may surprise all of us, that someone none of us suspected ends up on the thrown? it's actually what I hope that happens because GOT was never meant to a fairly tale.
I could be wrong?.. but that to me is what makes GOT to be different and among the best written shows ever made.
