During the Fourth Great Ninja War, the army of White Zetsus were a major problem because they could perfectly replicate people they'd touched, such that the Byakugan and other sensory abilities could not distinguish them. The solution to this problem was Naruto using his Nine-Tails Chakra Mode, which allowed him to sense the hatred and anger of the Zetsu.
However, this doesn't make sense to me. White Zetsu behaves like a child a lot of the time. For instance, chatting easily about poop and having a rather carefree attitude, sometimes even whilst in the midst of battle (during the Kage summit, for instance). Does White Zetsu really harbor such negative emotions that it would allow Naruto to distinguish him from his own allies, who, being adults in the midst of a brutal war, would undoubtedly be harboring just as serious negative emotions? What I'm trying to get at, is I believe that the Shinobi Allied Forces hate White Zetsu, but I don't see any compelling reason to suspect White Zetsu hates them. Of course, It's entirely possible I've misunderstood something or overlooked something.
So, my question is this: is there something I'm missing here, either with regard to White Zetsu's emotional state or to Naruto's powers? Are there any specific instances where White Zetsu's negative emotions are apparent?
