User blog comment:Stone Roger/Natsu and Zeref have somekind of relation?/@comment-90.221.52.199-20140316214948/@comment-24.52.205.15-20140414232948

I am also beginning to think that Zeref does has relatives still alive. When he confronted Hades and the rest of his guild, he mentioned that after a particular day, he learned that value of human life (Chapter 250, page 6). To me, this makes me think that a birth happened - perhaps a child or younger family member?

However,the above page could also be referring to when Zeref turned (helped turn?) Acnologia into a dragon then proceeded to start a war decimating everything. Especially since further pages said that his magic became more deadly. Perhaps it is in punishment?
