You’d aid he weaker, Spriggans are not a single person mind you. And that is where you are wrong, before the big battle, natsu said he will do everything he can to win, which includes murder because if he doesn’t win, FT loses, it ain’t like the past fights where he doesn’t have to murder. That only proves Dimaria is strong enough to survive attempted murder. The proof is in END’s powers which is to surpass god powers, that includes Zeref’s immortality. Again, power levels doesn’t matter with END since he simply surpasses God powers in general. Anne I told you, surviving attempted murder/killing blows is a sign of strength in this case. That is because before Alvarez he doesn’t have to murder, this time he has to do it in order to win. Yet Zeref did not die, that is because he is immortal, you are not proving a thing by saying that, that is the whole point of the discussion
