You are right natsu problably is end the demon but if he finds out he will want to die instead of killing his freinds so he will ask his freinds to kill him if anything happens. They will most likely refuse gray will hate natsu even more and they will end up helping natsu and he will become master of the guild or something. Or he will kill one of his freinds and go on a rampage killing everything  and end up dieing himself or someone will prevent the book from being opend gray will hate natsu and end up killing him ethir way someone has to die or it will just be boreing.
