In addition, the sharingan appears to grant photographic memory, yet forgetting is an essential part of coping with loss. Because while a trauma may never completely fade, the pain will lessen. But for someone who can remember his loss as vividly on the 300th time as he did the first, such essential aspects of coping would not apply.

Furthermore: There was plenty wrong with the world, and people like Madara and Sasuke were right in their observations. The conclusions they drew were not correct, but they did see all the evil and wrong in the world, and felt that only they had the power to change it.

While madara correctly noted that the world had been at war for thousands of years (and so the villages didn't change that), he didn't notice that the nature of war has changed considerably. In Kaguya's era there was permanent strife between everyone, in the Warring States era there was war between clans and in the Village era there was war between villages. Yet it went from everyone participates to only clans participate to only selected people of the villages participated.
