Sam and the death of his brother and father

[maiden of tarth]

Will this come back to teach Dany a harsh lesson? It’s mentioned a lot that one of Roberts better qualities, is that he pardoned enemies and made them friends. Tyrion begged her not to kill Randyll and Dickon. Sam seems really angry about it. He’s usually quite rational where rules of conflict and war are concerned but doesn’t seem to agree with Danys handling of his father and brothers refusal to bend their knees to her. Will Sams anger and her refusal to pardon, contribute to her potential downfall?
