I am sorry, but I am going to have to disagree as well.
I mean, it is an inspiring and compelling story and all, but if I come to work after my parents pass away, should I be considered a hero? It also does not help that Nigai was far superior in her program and Rochette got some very "generous" marks with all the mistakes in her program.
As I have stated before, anyone doing what they were going to do no matter what the surrounding circumstance is really not a hero. More dramatic? Yes. Heroic? No.
If you are just going by the pressure, then what Kim Yu Na did was FAR more impressive. The expectation from Korea on Kim was overwhelming (it really was out of control), which could have crushed any lesser skater.
