No normal, well adjusted human can withstand the fame and life that he had. You add in Jackson’s upbringing and it’s surprising he didn’t go out sooner.
That is why some of the vitriol here is so ugly (to me). Isn’t there something about ‘walking a mile’ in another’s shoes? Can any of us imagine the life he led? Always somebody wanting something. Not a healthy way to live...mentally or physically. If he was abusing drugs, like Elvis, who can’t understand what ‘drove’ him over the edge?
