No matter how strong, smart and rich a man was, it could be almost impossbile to prevent messy disputes over family issues, if you have more than one wife.
At the final stage of his life, when both his physical and mental health are degenerating, who really care about him? His family members only concern about the controlling power of his empire after his death. His lawyers are aiming to get greatest share of the fee through a series of lengthy lawsuits. The others like you and me treat him as a joke and the whole matter as a soap opera.
