Why are you bring Kojak's brother into it? 
It was Stannis who had his daughter burnt.
And that scene like others are based on Greek myth;
"Agamemnon offends the goddess Artemis on his way to the Trojan War. She retaliates by preventing the Greek troops from reaching Troy unless Agamemnon kills Iphigenia at Aulis as a human sacrifice."
And the scene were Arya Stark serves up Walder Frey's sons to him in a pie is also based on a Greek myth;
"Atreus then learned of Thyestes' and Aerope's adultery and plotted revenge. He killed Thyestes' sons and cooked them, save their hands and heads. He served Thyestes his own sons and then taunted him with their hands and heads. This is the source of modern phrase "Thyestean Feast," or one at which human flesh is served."
So GOT is a cross between Greek myth, the internecine feuding of the Plantagenets and the Wars of the Roses. Except Henry Tudor had no dragons.
