Otsutsuki Clan members are the strongest characters in Naruto but to achieve the power and become strongest in the Galaxy. They destroyed several planets for reaping the Chakra fruit and used all the life energy on the Planet’s and completely destroyed the planet.
They destroyed several different patents just for a Chakra Fruit and that is the reason why they are very strong in the Boruto series. They literally destroyed several Civilizations across the world in order to become more powerful. They committed Genocide across many planets without even giving a thought about the people living on the planet. Which is the most Awful thing that Otsutsuki did in Narutoverse.
Great Things that Otsutsuki did in Narutoverse
Otsutsuki’s are always a trouble to earth and to all humankind and the only thing they ever wanted was power or to consume a Chakra Fruit. The only Goal of the Otsutsuki is to destroy planets and consume as many Chaka Fruit as they can and to achieve Godhood or to reach the power of Otsutsuki God and become the strongest celestial in the whole galaxy. But knowingly or unknowingly some of the Otsutsuki Clan members did some great things to the Naruto world.
5. Kaguya Stopped Wars

Kaguya even though she made everyone on Earth her slaves and used their life energy to become more powerful. She also stopped the terrible world wars happening in that era. The wars in that era are always fierce and terrible and they caused massive death of people. But after Kaguya consumed the Chakra Fruit and used the Infinite Tsukuyomi and she stopped the terrible wars and deaths of so many people. Which is one of the great things that Otsutsuki did in Narutoverse.
4. Momoshiki and Kinshiki Attack

Kinshiki and Momoshiki’s attack in the Chunin exams is a sad and terrible thing in the Boruto series. But indirectly the Otsutsuki attack became one of the key things in the Boruto series because Boruto is the main protagonist of the Boruto: Naruto Next Generations series and he didn’t have any interest to become a shinobi and used all the other ways to get acknowledge by his father ( Naruto ).
But after Kinshiki and Momoshiki’s attack and Naruto going into full battle mode. Boruto understood the true power of Naruto and how great Naruto is and changed his way of thinking towards the Shibnob world and Hokage role. Before the Otsutsuki attack.
Boruto didn’t even want to become a great shinobi like his father but thanks to the Kinshiki and Momoshiki’s attack and the power of Naruto boruto realized the true meaning of the shinobi world. Which makes it one of the greatest things Otsutsuki did in Narutoverse.
3. Hagoromo maintained peace in the new world for several years

Hagoromo Otsutsuki is the elder son of the Kaguya Otsutsuki. He received the most powerful visual powers of the Otsutsuki Clan which is Rinnegan. After finding out the true nature of his mother and about the enslaving of humanity. He stopped his mother with the help of his brother Hamura Otsutsuki and defeated his mother.
After defeating his mother Kaguya, Hagoromo maintained peace for several years on earth. There weren’t many wars or massive destruction in his period of existence. He even acknowledged so many people by helping them and made humanity much more strong. He even invented Ninshu so everyone can express their feeling to others without even talking. But although it does not go as planned. But he did maintain peace until Indra became powerful.
2. Kaguya betraying Isshiki Otsutsuki

Even though fighting with her Clan members is a prohibition of the Otsutsuki Clan Rules. Kaguya almost tried to kill her partner Ishikki Otsutsuki because of the bond that is formed between Kaguya and the people on earth. She betrayed Ishikki Otsutsuki and saved the earth.
Although she did terrible things on earth after betraying Ishikki Otsutsuki. But this is one of the greatest things that Kaguya did on Earth because if Kaguya didn’t betray Ishikki and defeated him. Ishikki would have long before planted a god tree and reaped a chakra fruit and would have destroyed the earth even before starting of the Naruto Series. So this makes it one of the greatest things that Otsutsuki did in Narutoverse.
1. Hagoromo Sharing his Chakra with Others

Hagoromo Otsutsuki was the main reason for the existence of the Shinobi World. If he hasn’t shared his chakra with others in his journey across the world and formed a new form of power Ninshu there won’t be a Shinobi world even exist. He is pretty much the main reason for the Chakra and Shinobi world we have seen in Naruto Anime.
If there weren’t shinobi on Earth then Ishikki Otsutsuki would have easily taken over the earth because they weren’t any strongest people on earth or even the concept of Chakra and Kaguya was also sealed so there will be no one to stop him. So the Chakra sharing with other people and also the system of Ninshu made Ishikki wait for the opportunity. Which makes it the greatest thing that Otsutsuki did in Narutoverse
