If you go back to the tartaros arc after the dragons destroyed all the faces you see Igneel stating that they have stopped Ends resurrection. That alone suggests that End is evil and plus Igneel had told Natsu specifically not to open the book under any circumstances which suggests that something is sealed inside of the book.
