Eragon and Nasuada are both well loved characters with a lot of good qualities, but they also have some serious flaws and make some grave mistakes. For example, I feel they're objectionable treatment of Murtagh has been discussed relatively often. However, I think they need Way More criticism for how utterly negligent they were in preparing for the confrontation with Galbatorix. Without the outside benefit of genre awareness, it's so egregious how they almost never even try to come up with a plan to kill him. I feel like it springs from inexperience, being overwhelmed, and arrogance, but it's so severe because the ramifications extend to countless lives beyond their own. And no matter the reasons for it, neither of them ever then acknowledge this failing and amend for its consequences, and that is inexcusable. The fact that the first and only plan they ever had to defeat Galbatorix (which immediately fails btw), Eragon came up with hours before the final battle is honestly sickening. Considering their war is justified by a moral basis, the Varden's ethics, specifically in their leaders are all but non-existent.

Why???!!!! It feels like they take no responsibility for their allies! Their concern for them is vague at best and doesn't inform their actions. It's as if they believe that because these people willingly joined their cause knowing they could die, they as leaders are free of blame for anything that happens to them, which is a naive and indulgent misconception. Their decisions still determine those people's fates! And in regards to the eventual fight against Galbatorix, that potential fate they're taking a chance with should they lose is all their allies being slaughtered, down to the very last man. For a start. But Eragon and Nasuada are too young to shoulder that weight as their stations demand and too arrogant to admit their inability, so they just leave it by the wayside.
