Of course he was a role model, simply for the way he worked his ass off to bring to the world some of the greatest music ever created. He was incredibly disciplined, focused and hard working. Why does his personl life have to be the main part of why he should be a role model?
Everyone does some questionable things in their life...he wasn't going around hurting people, or being mean...from all accounts he was a loving man, and loyal to his friends.
To all artists who care about quality, integrity and the pursuit of excellence, no matter what kind of art they do, whether it be music, painting, acting or dance, etc, he should be held up as a prime example of how to take natural talent and then work very hard to perfect it, never settling for anything other than the best.
On top of that, the way he handled himself in his last months is something to be admired and respected.
Freddie was a genius!!
