In Naruto, why did Dai Tu launch the Kyubi no Youko incident?

In Naruto, the most direct cause of the Kyubi no Youko incident is revenge, because after the third Ninja War, Uchiha Obito saw things he didn't want to believe, including Kathleen being killed by Kakashi. The root cause is that Juehe Uchihiro Shoko Asahara is actually pushing this thing, for peace of mind, but for resurrection. This is only a part of weakening konoha.

Uchiha Obito was originally a ninja aiming at Naruto, but seeing the cruelty of war, he saw his heart after Kakashi killed Nohara Rin. Full of resentment. Turned into a villain. So revenge became the direct cause. But this is not the root cause, the root cause is to achieve inner peace. Therefore, the biggest obstacle in their minds is Konoha Ninja Village, so it is very important to weaken the strength of Konoha Ninja Village, and the best time is to use the Kyubi no Youko incident to destroy Konoha.

After the third ninja war. The national strength of all countries will be lost, and so will Konoha Ninja Village, so it was a very good time to launch the Kyubi no Youko incident, and four generations of wives, Xinjiu, were going to have a baby. Is also the weakest time, then the probability of summoning Kyubi no Youko will greatly increase, and this opportunity cannot be missed. As long as she can pin down the four generations with the strongest fighting power at that time, Kyubi no Youko will destroy Konoha Village, and controlling blood eyes with soil will also increase Kyubi no Youko's strength.

The direct cause of Kyubi no Youko's incident is to destroy Konoha for revenge, which is his most direct cause. Behind the scenes, the fundamental reason for promoting this cause is Uchihiro Shoko Asahara's peaceful and absolutely glorious resurrection plan, Kyubi no Youko's control and the weakening of Konoha's strength, all of which are part of a long-term plan. Assuming that this incident did not happen, Konoha's effective strength at that time was very strong, not only for four generations, but also for Xin Jiunai and others.
