Sasuke not present in konaha rushes back and revives naruto
wrong, if Naruto is dead and is it over for every one include the one who said it.
Proof for Sasuke dead :
1- Sarada awakened MS ; which means one of these people is dead : 1- Sasuke 2- Sakura 3- Boruto or Mitsuki (obviously not)
2- Sasuke can sense Naruto ; so if Naruto's dead , Sasuke must come to Konoha (even if he didn't know about Kawaki's attack) but he didn't come
...............................
Proof for Sasuke alive :
If Kawaki kills Sasuke , he's gonna have his Rinnegan . (He had no dojutsu , it would be good to have a rinnegan and EMS , no ?)
Sonrone doesnt have to die to awaken MS just requires strong emotions probably from love for her parents
All people who awakened Mangekyou , saw death of their closest friends , family tho :
Itachi (Shisui's death)
Sasuke (Itachi's death)
Obito (Rin's death)
Kakashi (Rin's death)

I'm not saying you're false . I'm just saying that didn't happen up to now .
