Oh no! Expose your father's sinful ways so that the sins of the fathers will not be upon you.. and she did! She is a good person, but

To those that take pleasure in dishonouring, insulting and abusing their parents and the ones that gave them life before the entire world I have only this to say-
”Honour thy father and thy mother, that thou days may be long”- Exodus 20:12 (NIV)
It is not only against every tenet of Yoruba culture and common decency but it is also shameful and disgusting for a child to sell her father down the river for worldly riches and gold. May God forgive such a child.
May God also forgive every Yoruba elder that has applauded such an action and encouraged it for they too have children who, more likely than not, will reveal their own dirty little secrets after they have died.
