found these spoilers and not sure if they have been posted yet
He (Itachi) accepted his fate as he embarked on his mission.
To sacrifice himself...this was his mission.
In order to have stability in the "village", Konoha put up a false image.
The person with the leading role was Itachi.
To observe/supervise the movements of the ex-rivals, the Uchihas, and at the same time arranged to ensure the stability of the village.
The head of the Uchiha clan only let his guard down in front of his son, Itachi.
His (Itachi's) biggest mission was to ensure the harmony between Uchiha and Konoha.
Konoha and Uchiha can be said to be on good terms.
However, an unthinkable incident took place.
A mystery hanged in the past in Konoha of which someone tried to kidnap the baby in which Kyuubi was sealed.
However, the plan ended in failure.
However, the Uchihas requested to be segregated from Konoha.
In response to that, it seemed that the Uchiha clan once again was plotting a coup d'etat, and even Itachi could not stop them.
Neither could he abort the initial plan to ensure stability in the "village".
The mission's scenario was greatly changed.
To ensure the peace in the village, Uchiha clan must be destroyed...
Then, to make sure that the responsibility for the massacre of the Uchiha clan did not fall into Konoha's hands, the actual murderer Itachi, could not be killed either.
Tainted by the fate of the survival of the Uchiha's blood, he placed this matter into his own younger brother's hands
To the outsiders...
What follows after that must be recorded
It's concluded to be the best plan to ensure that peace prevails thereafter.
Not allowed to survive.
Suicide is not an option
You have to...
let the brother that you love end your life...
This is what Konoha wants and it must be carried out no matter what...
The mission that was imposed on Itachi
was to be killed by you...
This was the mission that Itachi was given.
For the sake of Konoha, he went against his clan and carried a burden that would crush normal people.
Itachi carries a stain in his name till the day he dies.
The future generation will continue to speak of Itachi
in Konoha, he will be known as a missing nin who knew not shame...
in other villages, a murderer who killed his clan...
he will forever be recorded in the Shinobi world as a criminal
he will not be understood by anyone...
This was...
Itachi's final mission
Itachi carried out his missions flawlessly.
However, he wanted to tell this to you only it seems
In your memories...he wanted to remain in your memories
not as a ninja, but as an elder brother
However, he was not allowed to tell you this from his own words
Even his most trusted peers in the Akatsuki (were not told)...
However, I have a responsibility
I spoke of the truth.
Sasuke, this is not recorded in history and this has never been told to anyone. This is the Itachi that remains in your heart...
... a return report
Everything for the sake of Konoha, throwing away his reputation and life
Hence, Itachi is a hero
Itachi is truly....
second one
