how much the author stretched Danzo and Hiruzen's demise, and by what means. I understand that MC wanted to milk these two for darkening points, but at the last moment the excuse used to protect them was too much in line with Chinese culture and disregarded the original world. After everything Danzo did, he was cheeky enough to punish himself arbitrarily and force Tsunade to defend him through moral and legal means, because of his past achievements, and not to "chill" the hearts of older generations in favor of a promising younger generation. Yet conceptually, this is exactly what should be done by Konoha's moral code that started from Hashirama, to sacrifice for the nurturing of the newer generations. No matter how dumb people are, they aren't so blind as to be morally kidnapped by Danzo, of all people. If they can put themselves in the position of Danzo and feel "chilled", then much more easily they can place themselves in the position of Naruto and feel his mu*derous intent. By doing this, they're practically saying that the elders can bully the newer generation to death, and this would turn them generation resentful to the extreme.
