I get Ozzy and what he was made out to be for years isn’t everyone’s cup of tea - no issues with that.
But end of the day he was a PERSON - the whole prince of darkness but was something he did to make money. Just like pro wrestling or actors in a movie - some people play a role because it makes them famous/infamous - hell, even a few posters do that.
Ozzy the person did a lot and people sometimes missed that because of the role he played for so long. He dealt with a lot of issues in his life - some of them very poorly for years. Thankfully he turned his life around and hung around much longer than many of his contemporaries.
Parkinson’s is a very rough disease - his past likely didn’t help, but also likely didn’t cause it either. Seen some fine people reduced to nothing with that disease - just like ALS - it can quickly take perfectly “healthy” people and simply take away their ability to do anything physical, while leaving you with a perfectly functional mind. It’s a tough one to watch. Thoughts are with the family and friends and the many fans.
