A lot of people complaining haven’t read any of the books or anything about the characters. Dany locked her former best friend in a damn vault in Season 2 breh. In a vault!!! To starve to death. She watched while her only brother had 375 degree melted gold poured on his forehead breh and said he was no dragon afterward
She burned the fukk out that witch too back in the day. It’s always been there in Dany. Her experiences since then pushed her over the edge. But she was always borderline crazy. Have y’all been watching or not?
Using violence against an enemy that tried to harm you is not "borderline crazy" unless you're prepared to say Jon was borderline crazy for hanging the people that betrayed him, including a child, and Robb was borderline crazy for hanging people and making the one that was forced to do it watch before he himself was hanged, or Theon was borderline crazy for killing those kids, or Jaime was borderline crazy for killing his cousin/pushing Bran, or Arya was borderline crazy when she....(well nevermind, she might be
), or Sansa was borderline crazy for smiling when Ramsay got ate by his dogs, or King Robert was borderline crazy for seeking to kill infants, etc, etc, etc. Dany killed people that raped and enslaved people, and didn't flinch when the brother that abused her all her life and attempted to kill her and her baby was killed. People are reaching like hell to ascribe insanity to those actions, especially when they don't do the same shyt for all of the other characters that have used brutal violence as justice.
Call her entitled, vengeful, angry, or unsympathetic in those moments, like most of the morally grey characters in the series, but its a stretch to say she was showcasing insanity because she killed people that wanted her dead. And it still doesn't justify the leap to her seeking out to hurt people that have never done anything to her.
