I just disagree with and frankly is wrong but the Tarley's absolutely did not have to die
They died to show her cruelty and potential madness,
There was no reason at all to wipe out an entire house
Sam is still alive. and now his father is dead primogeniture will apply it won't matter if his father diswowned him.
Primogeniture (English: /praɪməˈdʒɛnɪtʃər/) is the right, by law or custom, of the firstborn legitimate son to inherit his parent's entire or main estate, in preference to shared inheritance among all or some children, a child other than the eldest male, a daughter, illegitimate child or a collateral relative. In some cases the estate may instead be the inheritance of the firstborn child or occasionally the firstborn daughter. The descendant (often the son) of a deceased elder sibling (typically elder brother) inherits before a living younger sibling by right of substitution for the deceased heir. In the absence of any children, brothers succeed, individually, to the inheritance by seniority of age (subject to substitution). Among siblings, sons usually inherit before daughters. In the absence of male descendants in the male-line, there are variations of primogeniture which allocate the inheritance to a daughter or a brother or, in the absence of either, to another collateral relative, in a specified order (e.g. male-preference primogeniture, Salic primogeniture, semi-Salic primogeniture).
The principle has applied in history to inheritance of real property (land) as well as inherited titles and offices, most notably monarchies, continuing until modified or abolished.

Is Dany hard and sometimes brutal? Most definitely but that is what is sometimes required of a ruler, or anyone, in GOT. Dany killing the Tarley's was brutal but it was also necessary. What was she supposed to do start a prisoner of war camp? What was Jon when killed the Nigh****ch traitors including Olly who was just a kid? Brutal and hard. What was Ned when he killed the Nigh****ch runaway? Brutal and hard. The people who aren't brutal and hard end up dead.
Big difference between killing traitors and killing those who won't bend the knee, though. As for brutality, Machiavelli, said that people rule through fear and love in the Prince.
In addressing the question of whether it is better to be loved or feared, Machiavelli writes, “The answer is that one would like to be both the one and the other; but because it is difficult to combine them, it is far safer to be feared than loved if you cannot be both.” As Machiavelli asserts, commitments made in peace are not always kept in adversity; however, commitments made in fear are kept out of fear. Yet, a prince must ensure that he is not feared to the point of hatred, which is very possible.

Yet, most think Jon would be a better King than Danny a queen.
