That doesn't mean END is a whole different being. You yourself said they just lose themselves. Natsu isn't going all evil, he had triggers to have done what he did in Chapters 503-505. Plus, don't you think there would be a resistance if END was someone else? "You think you can get rid of me? Naaaah"
