This plotline was left unresolved in the manga. Sasuke had a strong suspicion Oro didn't just attack the Leaf on a whim like he said he did. Oro's reaction and the fact these panels were shown at all strongly implies there was another purpose for his attack.
From part 1, we gather that Oro had a grudge against the 3rd for not making him Hokage. Yet the panels imply this is not the reason, but a different one. Jiraiya stated that Oro changed after loosing his parents. Therefore, I believe Oro not only had a grudge against Sarutobi, but also blamed the village for his parents death. The could have died similarly to Nawaki and rather than handling it like Tsunade did, he held a grudge.
On the darker side of the coin, I'd propose the idea that the grudge was more warranted. Perhaps Oro's parents were extremists, like himself, and muddled in forbidden affairs. They could have become very powerful and posed a threat to the village. Danzo could easily have orchestrated their deaths, even along the lines of having anbu ambush and betray them while on a mission together. If Oro found this to be true, he'd certainly have a real reason to seek vengeance.
Thoughts on the matter? Why was the issue never resolved? Will it be covered in the new project?
