I think what's happened with his death is that the pop culture zeitgeist is finally able to celebrate Jackson's musical contribution without the creepy, bizarre and downright ugly context of his fucked up personal life. The man was it for a period in the 80's - his beats were the best, his songs were the best, his moves were the best, his style was the best. I rocked a white glove when I but a wee lad not because I knew his music (I didn't) but because I thought Captain EO was the coolest thing I had ever seen.
All that had been eclipsed by his descent into a living caricature of celebrity. There is a sound bite on Roots Manuva's first album (or one of his first), I have no idea what it is from. It's an Arabic man (I think he's Arabic, his accent is pretty pronounced) asking some guy what Michael Jackson's problem is. He answers his own question by saying 'America makes Michael Jackson hate himself for being black.' I know that might sound extreme, but I think in the context of his career, it holds validity. He was going to sell 100 million records when 'Bad' dropped. He really believed that. When it didn't match Thriller's success, I don't think it's unreasonable to conjecture he fully embraced his epic program of 'de-racialization' and drastic plastic surgery. It was the pursuit of the ultimate form of celebrity, Jackson as the undisputed King of not only Pop, but of Music, Style and Fashion (culture?) that warped his thinking. The cocoon that his celebrity afforded him, growing every more remote, only exaggerated the process.
But now he's dead, and we can leave all that to the historians and sociologists. Nothing will burnish a career, while forgiving it's failings, like a pre-mature death. In the cultural landscape today, Michael Jackson is moonwalking, hopscotching across an illuminated sidewalk, traveling through space and just generally killing it (my apologies) with his superhuman skills. Everything that followed is diminished and ultimately rendered irrelevant. I'm not saying that this is right, or admirable, but it is reasonable. Popular culture has reclaimed Michael Jackson as he once was, before the megalomania and rumours and lawsuits: he was once the most talented man in the world.* This is why we put young Elvis on the stamp instead of old Elvis, it's why Marilyn Monroe is damn near a Jungian icon of sexuality and desire despite being drugged up and used by the end, and it's why Heath Ledger won an Oscar (no disrespect, as they say). Jackson's case is unique in that he ascended higher than anyone else (Elvis comes close, but he's not global on the scale Jackson was), and he fell further. Now that he's gone, it's as if all that weight bearing his cultural holographic imagery into the depths of mockery and disgust has been jettisoned.
This doesn't excuse him, if the allegations against him are true. In that case he is a monster; a sick and needing monster, but a monster nonetheless. In the shadows there will always be a shadow of Jackson as Grendel, the warped offspring of a lustful parent (although in this abstraction, the parent is played by a celebrity-stricken society). His physical transformation only serves to highlight this disjunction. Perversely, this dynamic acts to heighten the cultural and popular response to Jackson as he was, as opposed to as he became. Dig too deep into his tragic narrative and this same cultural/popular framework begins to appear deeply corrupt, destructive and ultimately empty.
But society is a funny thing, and perception becomes reality. He is now idealized in the hopes that the darker meanings of his downward spiral can be simply replaced, with the notion a young kid defying physics through sheer will and imposing his talent on a world that desperately wanted it.
*not literally, but in the context of the cultural mediasphere, sure
**wow, I don't really know what made me write all this. not a huge fan, I don't mourn his passing, but the social aspects of it are ripe for conjecture, I guess.
