Which character in Achebe's Things Fall Apart seems most haunted by the Igbo custom of leaving twins to die in the forest?

I think the character that was most haunted by that was Nwoye.

Nwoye

Explanation:

Nwoye is the character who is most haunted by the Igbo custom of leaving twins to die in the forest. Nwoye thinks this practice is horrifying and that it involves unnecessary cruelty. He is generally very sensitive to the cruelty that occurs in his culture, and this causes him to be considered weak and effeminate by Okonkwo. It is also the reason why Nwoye is open to the message brought by Christian missionaries.
