What makes the death of Okonkwo meaning (courage or coward) in Things Fall Apart?

From my point of view, I think we are meant to see
Okonkwo's suicide as an act of cowardice. Although you could argue that his death is
also an act of rebellion against the injustice of the British, the act runs completely
contrary to the beliefs and mores of the Ibo people. For this reason, it is an act of
cowardice.

His suicide is also the final act of
Okonkwo's tragic flaw as a character that we see throughout Things Fall
Apart: his near obsession with not appearing weak in the eyes of
others.
