Like I said above, END would have no reason to kill anyone besides Zeref, it could be that they are so beneath him that they are just a waste of time for him. Besides, I wouldn't say the same for those Alvarez soldiers burned to a crisp. That being said, if anyone stands in his way they would be in a world of hurt, honestly, with how the situation played out with Dimaria, either she stood in his way or Natsu had some sort of sanity left to protect Lucy before letting the demon take hold.
