Why did the Oracle call for Ikemefuna to be killed? What were the consequences of Ikemefuna's death on the tribe?Please provide three points for...

It is never specified exactly why the
Oracle has called for Ikemefuna to be killed. We only learn that the Oracle has called
for his killing as part of a ritual. The men in the tribe either don't question the
Oracle, or they do not share the reason with Okonkwo. Okonkwo is only told not to
participate, because Ikemefuna calls him father, and he is like a father to the boy.
Part of the theme of this novel is that the Ibo tribe often does things without knowing
why, it is just tradition, just ritual. The killing of Ikemefuna is a tragic
illustration of how the tribe has these beliefs and rituals that are often harmful and
illogical. One part of the ritual is that a father is not supposed to participate in the
ritual killing of his son, even if it is ordered by the Oracle, and Okonkwo goes against
this because he does not want to appear weak in front of the other men. Bad
decision.

Okonkwo's life falls apart after this because he
has taken part in the killing of his adopted son. His real son Nwoye becomes estranged
from Okonkwo at this point, never to return, because he loved Ikemefuna as a brother.
The tribe itself begins to fall apart after this as well. The younger people begin to
question some of the tribe's beliefs (like Nwoye) and begin to rebel against blindly
following things that don't appear to make sense to them. This eventually leads Nwoye to
accept the Christian religion.
