Good lord, lemme use the Google definition @Rachin123 I don't disagree with the not aging concept, but it is unfathomable for someone to sit back and say, "Immortal has nothing to do with being killed." School lesson: The root word "mort" means death. The prefix "im-" express negation, meaning not or "non-" Immortal means "Not dying." Back to Naruto, in Madara and Kaguya's case, you cannot kill them while they are fused with the Shinju because they'll just keep regenerating (Remember Madara recovering from being bisected by Sasuke or being hit by Night Guy?). Hagoromo and Hamura couldn't kill the TT, it had to be sealed.
