For Fang Zheng, using "Ratziel" to investigate all of this is easy, but he wouldn't do that. After all, Fang Zheng is not just an individual, he is the ruler of the Heavenly Dao Palace, and therefore in every world, when investigating every civilization and making decisions, he must have a set process, rather than just saying "according to Ratziel's records, this is how it is, so we must do thus and so"...
The Heavenly Dao Palace has its own guidelines, objectives, and clear concepts.
For example, in the argument between Nanoha and Little Sakura, the issue wasn't about right or wrong per se. As the saying goes, only children distinguish between right and wrong. For Fang Zheng, the real importance lies not in the motives or means, but in the results.
The desire for world peace could also bring about the destruction of humanity.
Conversely, an evil desire might become humanity's only guarantee for survival.
