The clan's reaction reveals that they believe that individual sacrifices must be made for the good of society and to guarantee strength and honor to individuals.
We can arrive at this answer because:
The oracle states that Ikemefuna must be killed on account of Umuofiana's death.
This must be done to create harmony in nature and ensure that locusts do not invade the region.
Everyone sees this as an obligation that must be done for the good of all and that there is no justification for this murder not to happen.
The oracle states that Ikemefuna's father, Okonkwo, is the one who must kill him, as this is the sacrifice he must make for the good of all.
Okonkwo feels terribly sad, but this is the role the entire clan is waiting to be played. Furthermore, failure to carry out the oracle's orders would cause Okonkwo to be seen as weak and selfish.
This question is about the book "Things Fall Apart."
