no,there are lots of ninja stronger than him
The Konoha Council and Danzo were the ones who told Itachi to kill the Uchiha clan.
Akatsuki didn't killed the entire uchiha clan. itachi Uchiha did. But it was a mission. Since Itachi Uchiha needed to kill the entire uchiha clan, Madara Uchiha knew everything what has happened. Sasuke Uchiha (The little brother of Itachi Uchiha) Is one of the 3 survivor's. When Sasuke killed Itachi, Tobi (Madara uchiha) told Sasuke the truth about Itachi. Since then, Uchiha Sasuke want revenge on konoha.
Danzo and the Konoha Council ordered him to wipe out the Uchiha Clan, who were planning a coup d'etat against Konoha. He made a deal with Madara Uchiha, who would spare Konoha if Itachi would help him wipe out the Uchiha Clan, who had betrayed Madara earlier. Madara agreed and the two wiped out the entire Uchiha Clan in one night. (With the exception of themselves and Sasuke Uchiha, Itachi's younger brother due to the fact that Itachi could not bring himself to kill his little brother.)
Uchiha Madara was a highly skilled ninja who lived years previously. He helped lead the Uchiha clan and was one of the founders of Konoha. He also trained Itachi. Madara helped Itachi with the Uchiha Clan Massacre.
Itachi Uchiha was 175.2cm (5'9'') in part one and 178cm (5'10'') in part two.
No, who told you that? No one in the Uchiha Clan really wants to kill him anyway. And if anything, it's his brother Itachi that almost kills him.
Sasuke Uchiha has one brother(Itachi Uchiha).
Many people think Itachi Uchiha is handsome, while others think Orochimaru is the handsome one.
Itachi seeked out madara to help kill his clansmen. this was an agreement so madara wouldn't attack the village if he help itachi kill the clan. itachi did kill uchiha shinsui and gained MS. it is proven and it has no evidence proving otherise. shinsui was the best uchiha next to itachi. the clan knew itachi to be a prodigy but did not know the extent of his power. this can be noted when 3 police officer came to question him about shinsui death and he took them out in 2 or 3 seconds. this is full 3 tome sharingan users. itachi abilities was unrivaled because he killed the best of his clan without a scratch. there was no visible wounds on him the next day. which leads us to believe he is extremely powerful. this was then confirmed by the elder to pick itachi out of all his clan members to carry out the massacar. he was the only one talented and skilled enough to do it. madara couldt kill the entire clan by himself and neither could itachi but together they could. remember this is the uchiha clan. the most formidable and known as a battle clan even a genius was just ordinary before them.
Deidara, throughout the entire Naruto series after he joins the Akatsuki, has a grudge agenst Uchiha Itachi, and all uchihas, because Itachi is the one who made Deidara join the Akatsuki in the first place. Deidara, while fighting Uchiha Sasuke in Shippuuden, chewed and ate some of his clay turning himself into a human bomb in order to kill Sasuke. He blew himself up but, unfortunately, instead of killing Sasuke, Deidara killed himself.
He has no girlfriend and eventually he dies in Naruto shippuden without a girlfriend
This might be a spoiler, but Sasuke kills Danzo because him and the other elders around the third hokages. People ordered itachi to kill the uchiha clan. Itachi was only staying loyal to the leaf village, but he left Sasuke alive and told the hidden leaf to keep him safe.
