Re: Jon Snow
Viserys is a scum, agreed. And Dany is basically a good person, no doubt. But the trouble appears whenever she tries to be a leader. The trouble of trying to be a benevolent despot, and forcing what one believes to be right on others. Does Dany have the right to kill people to further her experiments with the dragons so that she lay claim to a continent she has never seen? Just because she believes it belongs to her through her "noble" bloodline and her successful fire experiment with three dragon eggs? She doesn't.
Let me explain my point. The Braavosi fought their captors, escaped, and set up their free city (whatever its demerits- the bravos, the blood feud at the death of princes, the cult of banker-assassins, etc.). Danys comes serving quick freedom to the "lamb people", to Meereen, Yunkai, and Astapor-leading her dragons and her faithful along the way like, to make an apparently unseeming comparison, Napoleon bringing the concepts of "liberty, equality, and fraternity" to the populace of Europe. The slaves she frees look up to her as a deity; when in reality she is a good, but a really proud, adamant, and selfish teenager. Slaves learn best about freedom when they free themselves; they learn nothing of freedom when someone serves them freedom on a platter. Dany chose the easier way: the short-cut formula.
Short cuts don't work. At least never in societies and with people. The best solitary dragonrider, the fiercest direwolf with the best of intentions cannot usher in revolutions. They tend to fail, burn out, or die.
As Ned Stark used to say: "When the snows fall and the white winds blow, the lone wolf dies but the pack survives." Jon thinks of the pack and the big picture, Tyrion used to before he killed his pa, Varys does it in his own scheming way. Dany doesn't. I wish she did, though.
