I just finished watching the first episode of the final season of Game of Thrones, and as usual, it's a cinematic feat.
What struck me was the idea of "goodness" that Daenerys tells herself she pursues. She's portrayed as someone who sacrifices the principle of goodness, while claiming to do what she does in pursuit of achieving goodness for all people. In season 7, she mercilessly killed the Tarlys because they did not choose to bend the knee, showing that she demands unconditional fealty above all else, even hypocritically, at the expense of goodness.
In contrast, Jon Snow, in season 7, chooses not to lie to Cersei and and his people and reveals that she swore fealty to Daenerys, even if it was at the expense of having Cersei's armies to help fight the White Walkers in the North. Tyrion calls him out as stupid for being unable to lie, but Jon shows that he lives his values by saying "When enough people make false promises, words stop meaning anything. Then there are no more answers, only better and better lies." The audience is led to believe Jon Snow to be a more suitable ruler because of his honesty and compassion, so it's interesting how that's going to play out in season 8.
Thusfar, Jon has not cared for the crown, but his sincerity and belovedness as a leader might put him on the throne. After all, he's the Reluctant Ruler stereotype, meaning that he's less inclined to abuse power if given it.
