One main character taking the right lesson,The Other taking the wrong lesson?
Both Jon and Daenerys's ruling arcs in ADWD are parallels to each other,They rule The Night Watch/Mereen they do many bad decisions,it ends up backfiring in their face
The only difference is what got them killed/Overthrown,Jon didn't compromise,Picked a "My way or the highway",Hid many things from his own men who slowly started to hate him more in more and decided to desert the Night Watch to save who he thinks is Arya,He made the mistake to become too hated and never compromise,Broke literally all his vows and got executed for it.Meanwhile Dany she was compromising with the Mereneese and it did led to peace,But it also caused that many viewed her compromise as a sign of Weakness.And things ended up backfiring so she decides to follow "Fire and Blood" and unleash her fury on the world that rejected her.
We know that GRRM endorsed the Mereneese Blot which pretty much state that Dany should have continued compromising And that her stopping And Going "Fire and Blood" is selfish and is locking herself in the Bad Ending and would lead her to a dark path.
So could it possibly that the plan was for Jon to take the right lesson and Dany the wrong lesson.Jon post Resurrection would then become more honorable,Acting more like Ned Stark 2.0,He will bring justice to the Boltons by swinging the sword and follow more honor all the while compromising with his enemies to achieve peace
Meanwhile Dany she would think that violance is the easy anwser and unleash it on anyone who oppose her as it the only way it get results,To the point that her dynamic with her advisors(Jorah atleast) get reversed with them telling her to control her worst impulses,She will also stop caring about "Home" and "Family" and the "House with the Red Door",The Important thing is to get The Iron throne and SHE WILL GET IT!No matter the method.And if anyone oppose her or try to stop her from getting her throne,They are her enemy,"Dragons plant no trees,FIRE AND BLOOD"
Do you think that was George's plan if he continued writing TWOW?one would take the right lesson and become more compromising and honorable?while the other take the wrong lesson and decide that Violance is the anwser either becoming too Cruel(Like Tywin Lannister or Maegor the Cruel) or Outright Mad
