Answer:
In Okonkwo's clan, one practice that would be considered by them as barbaric is the act of euthanizing pets, which is commonly practiced in our society. While many people in our society consider this as a humane way to end an animal's suffering, it would be seen as a violation of the natural order in Okonkwo's culture. The people in his clan hold animals in high regard, often seeing them as companions or family members. The intentional ending of an animal's life is abhorrent to them, as they believe all life is sacred and must be allowed to run its natural course. Such contrasting beliefs regarding animal welfare are a testament to the vast differences in cultural values and practices across societies.
