Achebe's monster

The characters of my problem are me and the setting of my problem is on this world. I am struggling to find what I want to do with my life, so it’s pretty much self explanatory.
Achebe's monster I think is Okonkwo, because he builds himself up to be a strong person to avoid being similar to his father who is lazy and not respected by the community. Okonkwo wants to change his family’s reputation and by doing so he becomes so arrogant and over dominant that it leads to his downfall. Okonkwo became a monster to avoid becoming anything like his father. Rosseau’s savage is a person who is unchanged by society and has not been influenced in any way by society. Rosseau's savage is not illustrated in Achebe's book. The characters in Achebe's book are in a society and are affected by that society. The only way Rosseau's savage would fit in here is if Rousseau's savage was referring to people who don't assimilate to western culture.
