Technically Nick, Religion is merely a fancy word grouped together with Faith by corrupt or rather, practical(at the time) leaders once upon a time. Faith is faith, be it "religious" or otherwise. It is still what motivates someone and here Zeref is clearly Kyouka's motivation and like JenPa said, there is nothing wrong with being like that. Everyone has their own motivation and it sometimes strikes as odd and is many cases might drive you to do extremely cruel things in the name of said faith. Don't take this the wrong way though, I also found this development with Kyouka to be BS.
