Have a situation about goat, need help!?

I have a friend who owns a goat and it has infected ball, so one night when I got drunk I grabbed a scalpel and a chisel and cut the ball off. It is now sitting in my freezer, frozen - I chopped it, de-froze it on a frypan and let the juice simmer, incorporating vegetables into the stir fry. One night, I feed the stir fry to my family. Is this normal? I didn't tell my family what they were eating, they enjoyed there delicious meal while I sat in corner, inconspicuously.
