Spoiler: Why did Ron and Hermione let Harry go?

[nirupama76]

One thing that really bothered me in the movie was that Ron and Hermione just stood back and let Harry walk off to the forest alone. This part was handled very well in the book IMO. There Harry does not say goodbye to them knowing that if he does then he may not be able to walk away. It seems very out-of-character for Ron and Hermione to just stand back and let their friend walk to what is probably going to be his death.
