What I'm trying to point out to you is the hypocrisy of the characters as it's human nature and again the relationship between power and people. It's all perception because people have ulterior motives of what they want and try to justify with their own sense of morality. Each character is a contrast to real life applications - America says the middle East are where terrorists reside and we have to watch out for weapons of mass destruction but america is the only country to have ever used one.
The audience wanted to see Jon and Grey Worm fight but again there was no need to and if they were going to do things the old way it would have been trial by combat. You have understand, Grey Worm is not in a position to make the call because as much as they're trying to change things there's still that "Illuminati" of people like Sansa, Arya, Bran, Edmure, Samwell, Tyrion, Davos, and whoever was there who were gonna vouch and try to get Jon off. Again relationship between power and people.
Tyrion was just as loyal to Danearys as Jorah was, Tyrion had never sent info to Tywin or KL about Dany, her dragons or whereabouts the way Jorah did. Only thing that separated Jorah and Tyrion was that Jorah loved her. I brought Theon and the examples to show you none of these characters were killed immediately after committing treason.
If you didn't like the finale that's on you man. I have a different perspective on it because I'm adding up everything that happened throughout. The point of game of thrones are all the conflict between the people and wanting power. What makes it so entertaining is the way they all go about it. People all wanted Jon to be King but he didn't want it because of the bullshit that came with it. We wanted Dany to kick ass but we didn't want her to be the villain, we wanted Arya to kill Cersei but she couldn't get to her in time. The ending was left bittersweet which is ultimately what GRRM said how he was gonna end it and that's what we got.
