I wouldn't bet on that, Neko. His personal eccentricities, along with the allegations, complete appearance change, and odd behavioral antics, will not go away. There are far too many stories over the years for it all to just be wiped away from anyone's memory. Some of it was true, some of it was false, but it was all in plentiful supply.
Just about everyone has some songs from the guy that they like (Thriller, Leave me Alone, Billy Jean, Smooth Criminal... those are some of the one's I've enjoyed over the years), and just about everyone has opinions on his actions over the years. But regardless of how much anyone likes him, hates him, or is indifferent towards him, Michael's legacy will always be two-fold... his music career, and his personal life. The two will never be separated, as they're far too entwined with one another.
