While the initial cause was due to him wanting to revive Natsu, Zeref was or rather still is a case where he receive fame for the things he didn't do. Whenever something like Lullaby is used by someone, instead of user the credit goes to Zeref. Same with the etherious, everyone just link it back to Zeref.

If Avatar actually succeeded in their Operation Purify, i think the credits will still go to Zeref instead of Avatar.... ( ._.)
