HOW MY FATHER RAPED ME ‘ON DAILY BASIS

A 13-year-old-girl in Akwa Ibom State in Nigeria narrated how her father, Godwin Jeremiah, sexually assaulted her repeatedly in their home.
The victim spoke to journalists after the arrest of Mr Jeremiah, a bricklayer from Ikot Udota. she accused her father of forcefully having sex with her mainly in the night, and almost on a daily basis. She also said that her father’s friend, one Mr Michael, from Ikot Udoma village, also attempted to rape her, but he ran away when she raised alarm.
“she said her father forcefully abused her sexually. This occurs almost on daily basis in spite of her resistance and the pains and injury she sustained from the ungodly act. “Initially, she reported the case to her stepmother who confronted her father, but she was beaten and this made her flee from her father’s house.
“When the whole thing became unbearable for her, she ran and reported to the police, which led to the father arrest, but she said her aunt, who did not believe her story, intervened and she was released on bail.” The girl said after her father’s release, she did not have any option than to return to the house and stay with him. “The matter grew from bad to worse. It was the darkest moment in her life. She said her father did not allow her to sleep, he forcefully abused me throughout the night.
“It was coming on daily basis. Since nobody was there to help her, she said she decided to run away from her father’s house. “But fate led to her meeting a compassionate mother, Mrs Bright Archibong, and the President of FIDA who rose up to fight on her behalf,”
The News Agency of Nigeria (NAN), reports that the DPO was accompanied by the wife of the Eket Local Government Chairman, Bright Archibong, and President, International Federation of Women Lawyers (FIDA), in Akwa Ibom, Emem Ette, to arrest the alleged suspect.
My question is::
“It is the worst thing a person can do to a child, especially a father to his daughter. What could have caused a father to rape his daughter?”
What could have caused a father to do such thing to her blood?
