Why didn't Uchiha Itachi get himself the Eternal Mangekyo Sharingan?


To make an Eternal Mangekyo Sharingan, you need to transplant another Mangekyo
Sharingan, right?

Itachi had awakened his Mangekyo Sharingan when Shisui died, and Shisui had
gave his eye to Itachi. So why didn't he transplant that eye and make his
Mangekyo Sharingan eternal?

As for the reason why he did not use his father's Mangekyou, it could be
because Itachi knew that he was dying and saw no point in achieving Eternal
Mangekyou, just to die to an incurable sickness. He probably knew he wouldn't
have enough time to reap the benefits of the Eternal Mangekyou. For more info
on his sickness check out this thread; [was it ever stated if Itachi was
already dying?](https://anime.stackexchange.com/questions/48553/was-it-ever-
stated-canonically-that-itachi-was-already-dying-when-he-fought-sasu)

The last reason is what I would call " _ **an overwhelming level of Love mixed
in with a strong guilty conscience**_ ". Itachi wiped out his entire clan to
protect Konoha from the coup that the Uchiha were planning, but couldn't kill
his brother because he loved him more than everything else. Itachi most
definitely knew how terrible his acts were and right from that moment planned
to make amends for it by dying at the hands of his kid brother, who would try
to avenge the entire clan. Itachi most likely also concluded that Sasuke would
have had no chance against him if he had the Eternal Mangekyou, and therefore
decided to really fight his younger brother later on after his eyes had
deteriorated in such a manner that they would be close in strength and not a
one sided battle.

So it was actually because of Sasuke! He knew he was dying and preferred to
die at his brothers hand. By doing that, he used his death to make Sasuke
stronger. In order to make the fight a bit fair, Itachi decided to let Sasuke
have the upper hand (by fighting him while he was partially blind and sick).
