He was $400 million in debt and would probably never be out of debt. At 50 he was killing himself rehearsing and writing songs for a massive tour. He was weak and fragile even then and probably felt that he could not pull this off.
Hell, international touring with a massive show has got to be alot of pressure and physically demanding even when you are young and fit. Mebbe he just though this is just all too much. His life was insane anyway.
Dunno. I think he might have “facilitated” this. We many never know. But he sure had alot of reasons to do it.
