Sure, but that ignores context a bit. You said she’ll burn anyone who disagrees with her. The Masters (and Unsullied owners) were monsters who mutilated, enslaved, and sold men, women, and children. Yes, her motivations weren’t completely altruistic there, but she was also clearly disgusted by the practice and managed to damage the slave trade quite a lot.
And the Dothraki abducted her and were going to essentially keep her prisoner forever and likely rape her as they saw fit. Because that’s what Dothraki do.
That’s more than some disagreements.
I’m not trying to say Dany is a saint. No one on the show is, and she’s definitely got a body count that’s crazy high. But it should also be remembered that the war never really ended for her. She was in exile and hiding since the day she was born with the constant fear of Robert or the Lannisters coming to kill her (whether that was a legitimate concern or not doesn’t really matter, it’s what she grew up believing). So yes, she has a bit of an obsession with getting back what was taken from her family.
Really, she and Robert have plenty in common. Both are starting wars because something was taken from them that they want back. For Robert it was Lyanna, for Dany the Iron Throne. We know that Robert must have been good a good leader and a conqueror. Because he did those things (and lets not pretend that war didn’t have a high body count). We’ve also seen that Dany can inspire those to follow her and that she can conquer. Robert would have been around Dany’s age when he took the throne and likely had little practical experience ruling. So it’s not out of the question that Dany could be a good ruler at the end of the day if given the chance.
I also would hold against her that she’s never picked up a sword on the battlefield. She’s not Brienne. She doesn’t have the training or physical strength to stand toe to toe with a man in battle. So she used the weapons she has at her disposal. In her case it’s dragon fire. And who would use that if they had the option? Characters like Dany and Cersei can’t play the game the same way the men do, but I guarantee every would be King in the series would have gone nuts with those dragons if they had the chance. So far Dany’s shown a decent amount of restraint considering the power at her disposal.
Also, it’s a bit weird to get on Dany’s case about burning folks alive shortly after praising Stannis as a good king when he burned lots of people alive. Innocent people. Including his daughter. Just so he’d be king.
