Why do coffee beans need to be roasted?

Can you answer Richard’s question about Coffee?:

What does roasting do for the coffee?

I am thinking about juicing beans, to create a very strong cup of coffee, that does not have any burnt taste.

For this I believe that I should use un-roasted green coffee beans.

I have a lot of ignorance in this area though and need help and suggestions.
