what was the final action Okonkwo's did and was it heroic or cowardly and why, in Achebe's "Things Fall Apart."

The missionaries, along with politicians, meddle in the traditions of the village, angering Okonkwo. Okonkwo sees more and more signs that his village is not the village of warriors that it once was. When he sees that the other men refuse to stand against the missionaries and politicians, he kills himself. Okonkwo's suicide can be interpreted in a few ways. Is it heroic? Is it cowardly? I think his actions speak to the culmination of his loss of identity and control. This ties in with his perceived loss of masculinity: a masculinity that he was obsessed with.
