We've been reading a lot about Michael Jackson over the past day and this article at Slate.com is the best we've seen. They basically say Michael Jackson was committing suicide, albeit a slow suicide over many years. They talk about his painful childhood years and his rise to fame. They also mention his physical transformation;
... an entirely transfigured physical appearance, morphing from an engaging and handsome African-American man into a misshapen Eurasian woman; his skin bleached, his face re-sculpted; his nose, finally, needing to be practically taped onto his face. He left his race behind and, in a sense, his family too. (The nose, which seemed to have borne the brunt of his obsession with plastic surgery, was his father's.)
