can neji come back alive?

Nah,, he's dead and will stay dead

I mean i'm sad abt it too but that's just how life works 😔

He didn't have to die could have used Eight Trigrams Air Palm hoặc Eight Trigrams: Palm Rotation.

In some cases other countys use jutsu to bring the person back and if that happen to niji then he will not be happy to be alive. But he should know what his porpose in the moment to do bạn might have saw what happen to hayate he was used for that and he did not want that.
