I do think that Tonya greatly needed better mentoring off the ice. I've wondered so many times why Rawlinson was so here.
Rawlinson always said that skating was Tonya's ticket out of the gutter. But ultimately, she was mistaken. Her ticket out of the gutter would have been a wholesome family environment that would have helped her acquire a sense of well-being and heal from the scars of her past.
In fact, success in skating might have even intensified Tonya's problems. If she had retired before making the World Team, I doubt she would've ever gotten involved in a serious crime.
Anyway, it's a common misconception that success and achievement automatically leads to personal happiness. And Tonya's life clearly shows that to be wrong. A far better bet is to focus on someone's personal well-being and character. If you build that up, success is much more likely to follow. And even if it doesn't, the person will have important life skills to help them in the long run.
