kind of surprising that even though a dragon killed his entire family, Zeref was never shown holding any grudge against any dragon. Sure there's a feud between Acnologia and Zeref but thats more so to them having different ideologies. Actually i'm not even sure what purpose Acnologia serves in this story. He just comes off as some random fuck that decides to show up at random and mess things up.
