Considering how "permanent" Gray, Lisanna and Jackal died, I don't think killing Natsu off just once would take him out of the story.

That'd be a nice plot twist, if Natsu died and to the surprise of himself and the present Demons rematerializes in one of those ressurection tanks.

Or if he was absorbed by Franmalth and once Franmalth is getting close to running out of juice, Natsu, Aries, Taurus and all the other Souls he has captured start a "revolution" inside of the Demon and destroy him from the inside out.
