I have to say, what a misleading title. I don't understand why you wouldn't grieve the passing of human life, but would grieve the "passing of talent". Like or dislike his life, he is unarguably the most influencial person in the history of music since Elvis and The Beatles. He didn't waste his talent and we don't have the right to judge whether he wasted his life or not. Good or bad, his family is still grieving the loss of a son, brother, uncle, cousin, father.
