Is it fair to say that Daenerys attitude went something like the following.
Daenerys: "We Targaryens brought law, order and civilization to the filthy savages of King's Landing. And all they did is kill my poor father as a thank you. They deserved it."
Its not as if it was entirely unprovoked. This point is covered multiple times throughout the story. But somehow it appears that people don't get it?
They don't get that burning king's landing was revenge for the mad king?
No, because Dany never knew her father and didn't seek the throne in order to get vengeance for him. Dany wasn't so naive to think that the reasons for the rebellion against him was completely unjustified. But still, her birthright still existed, and her having the means meant she could justify wanting the throne back.
It is unprovoked though... what did the people of King's Landing do against her? Kill the Lannisters all you want, just like you did the slave masters... don't kill the average person. They had nothing to do with her family's downfall, that was Aerys II himself and the sycophants around him that did nothing to end his reign and crown Rhaegar instead.
Dany is going to have a rude awakening when she comes to Westeros. In the books most of those that would have supported her will be backing Aegon (Young Griff). Like Stannis she will see she can't take the throne by force without a cost to HER realm, so she'll go North to protect it, like any other decent leader.
Daenerys is the only character in the era with vision and the influence to cause real and lasting change. She was the only one who cared about freeing slaves and helping the poor. With Daenerys as leader, real progress would have been made in the sciences, arts and society. Civilization would have taken many steps forward. With anyone else as leader, they wouldn't have accomplished anything aside from reinforcing the same boring old traditions and flawed cultural standards.
None of the characters in the story understand what was truly at stake, or what they lost by pressuring Jon Snow to kill her.
None of them can see past their own small petty grudges and revenge. Daenerys is also guilty of this when she burns King's Landing. In that sense, they're all equal and guilty of the same failing.
I'm not going to act like Dany wasn't unique, she's a revolutionary. But the reason why she can get shit done isn't only because of that and the loyalty she inspired, it's because she has dragons.
Jon Snow had to kill her, she had lost her mind (inexplicably, but that doesn't change what had to happen).
I don't remember the motive behind Jon Snow being killed.
Did it have something to do with him refusing to bow to peer pressure?
That's a good point about Jon Snow feeling like he has to try harder and do more to compete with Robb, etc.
But TBH I don't remember much of what happens.
It was due to his attitude towards the Wildlings and elements within the Night's Watch that thought he was betraying what the order stood for. Oh and also racism.
If you want to focus on peer pressure, then yes, his support of the Wildlings in order to protect humanity as a whole is a refusal of him to back down. But there's more nuance to it given that he lived among them and saw they were just like anyone south of The Wall. But like I said, there's examples of him being rigid in his thinking for the better as well as being malleable for the better.
It wasn't competing with Robb really, it was finding a place he belonged. Life at The Wall was harder than he thought and he realized he had it pretty good at Winterfell. He wanted to support his brother in avenging their father like any normal person would have. Little did he know that Robb made him his heir before he died... well little does anyone know. But that will be a big factor in the story going forward, unlike it being shown in the show and then completely forgotten about in the dumpster fire the show became.
