There are quite a few fanficts that retell parts of the story in ways I consider better than the original (I even had a few people say that about my own fanfict :D #shameless plug) , but this isn't one of them. As Misk pointed out it makes no sense for Natsu to want to kill everyone just because Lucy was supposedly killed. Which is the reason for him freaking out like this, if you remember, along with the Ehterious inbuilt instinct to kill Zeref.
