Absolutely! Had she lived a bit longer, I am fairly certain that his life would have taken a different path. Her control over him may have been limited later on in his life, but I believe that he loved and respected her so much that he would have had to keep himself a bit "cleaner", if you get my point. I also think that his state of mind would have been far different because he would have had her to confide in and that would have eased his mind greatly. I think that when he lost his mother, he lost the sense of being loved unconditionally...which could also explain part of his adoration for his fans, since we loved him unconditionally too. But he just lost something integral when she passed on, and had she been able to be with him for a while longer, she could have had a huge impact on certain situations and their outcomes.
