My father is suffering from cancer he is on casodex one a day
He vomit blood and black stool due to esophageal varices (condition due to liver problem)
He was HCV possitive but PCR test reveals not detected .
My question is that is casodex is destroying his liver ??
Yes, Casodex can cause liver problems! Stop with Casodex and see the doctor!
If he has internal bleeding (black stools) and esophageal varices, Hep C is a bigger risk than prostate cancer. Sofosbuvir (Sovaldi) can cure it.
It may not be related to the Casodex, but I would certainly want to immediately get him in to see a Gastroenterologist. The esophageal varices can be life threatening if one happens to break and start leaking. There are ways to examine them and to treat them if active bleeding is confirmed.

The esophageal varices often develop as a result of livers that have been damaged by chronic viral diseases or other liver traumas. This can result in an over-pressure in the portal vein, and the nearby veins in the esophagus and stomach. They swell up, and can eventually leak or burst.
I'd want to stop the bleeding first. Then treat anything dangerous in the the liver. Then resume/continue prostate cancer treatments.

If he already had esophageal varices he most likely already had a liver problem. However, bleeding and black tarry stools with the varices could be life threatening. Call his doc ASAP.
