So, looking at the two texts you can become very divided on, whether Scott was a fool, an idiot or if he was a humble hero who fought to the end.
Some people would say he is a complete idiot for even daring, such an extreme thing, daredevils however, would probably call him very brave.
Now, I believe Scott is more of an inspiration, which also makes him some kind of a hero. What I think a lot of people tend to forget is, that no one really knew how bad it would be.
There were not any accurate weather prognoses for the south pole at the time so, no one would know what a realistic answer would be based on how much food was needed, and how much clothes you should wear for such expedition.
