To me Okonkwo would be a tragic hero because my definition of a tragic hero is someone who works his way to fame or starts off powerful but has one flaw that will  lead to his death. Although there is no evidence of Okonkwo dieing, he has worked his way to being powerful but it seems as though Okonkwo emotional instability, will cause his tragic fall. There is also evidence in the story where Okonkwo's anger gets the best of him, which foreshadow tragic downfall.
