Justice in Gundam Seeds is narrow and one-sided, and both Yamato and Aslan only represent their own justice (Yamato represents a natural person and Aslan represents a new human being).
From the above, we can see that the world views of the two Gundam books are completely different, so the world they show is also very different. 00 to show the world as a whole, express human views or yearning for peaceful and intelligent life beyond human beings (that is to say, they are eager for communication and understanding between lives and have a strong tendency to peace), close to philosophy (relatively easy to understand), while seed shows the world on the basis of camps (natural people and new humans) and expresses human views on freedom, nature and ethics (more inclined to affirm self-worth, and)
Simply put, the world as high as 00 is generalized, and its contradictions eventually changed from internal contradictions to external contradictions. Gundam seed's worldview is narrow, and its contradiction has always existed internally (that is, it has never been unified). This is the world they show.
Therefore, it can be seen that what Gundam 00 hopes to convey is that people should understand each other (and will certainly understand each other). Only in this way can we achieve real unity and usher in real peace; What Gundam Seeds wants to convey is: it can be said that the importance of human self-affirmation and others' self-affirmation, and it can also be said that it expresses people's desire for identity and survival (in fact, I am not accurate in saying this, because there are too many political factors and conspiracies in Gundam Seeds, which gives people the feeling that the theme is unclear).
On the other hand, the detailed description of Gundam Lee pays more attention to "twists and turns in the process of success" (from the denial of heaven and man to the recognition, from the smooth beginning of heaven and man to the unsuccessful end), and describes the personal feelings of the characters relatively less; There are relatively many descriptions of personal feelings and various emotional entanglements in Gundam Seed, which is also caused by the size of the world outlook in the two works.
