Ozzy never believed in God or the Devil when he was young, he never paid any attention to it and it was all for show.
Through Alcoholism he became possessed by a very real Demon. One night he almost killed Sharon, he tried to strangle her to death, and she realized something was different, black eyes.
Sharon forced Ozzy to goto a Shaman who removed the Demon. Her love saved his soul and he knew it, a changed man.
