Such a detailed writeup in this issue. Thanks for the great insight. Let me react to this:

some brutal family fights that resulted to more deaths in the family.

The ikwunne system of sharing inheritance like you said have resulted to wars within. Especially when the deceased have children who are capable and are to be left with nothing when the father is wealthy. I use to ask if that traditioned will be amended in the future, seeing that it has probably caused more harm than good. @scribal
