What ever may have been shown may have been according to Zeref's desire, but now that Natsu knows about his demon side and his connection to Zeref, he wouldn't go in guns blazing like last time, he would find a different way to defeat Zeref, maybe lock him up for all eternity. He doesn't want to make his friends sad, that is his belief as a human.
