Thought on Things Fall Apart

Things Fall Apart by Chinua Achebe isn't exactly a book that I would really enjoy fully, but some moments in the chapters I have read so far have left me questioning and anxious.  Okonkwo is a character that I am not particularly fond of.  One reason is because Okonkwo doesn't seem to be able to control his anger and need to control.  I understand coming from the background he grew up in, it was kind of inevitable for him to turn out this way.  Although there is always room to change, he is always so hard headed and short-tempered.  Beating his third wife on the Week of Peace shows that his swarming emotions are way too much.  Also, killing Ikemefuna, whom he was quite fond of, just because he didn't want to be seen as weak?  That seems like utter nonsense to me.  I know that he himself was a little shaken after killing Ikemefuna, but I feel no sympathy.  He chose to stick his hand where it shouldn't have been and he paid a small price for it.  Okonkwo is a very faulted man from what I can see, and so far throughout the novel I see no improvements in his personality and demeanor at all.  This is quite unfortunate but I do hope to see a change in Okonkwo soon, because after all, he is the main character for this story.  I've already read more than half of Things Fall Apart, so the moment when Okonkwo changes shouldn't be too far ahead.
