This is for anyone. Free will??

Ok, this is for my final in a philosophy cl, but I am interested in what others think..... Do we really have free will? Personally, I think there are some things we do not choose, such as who our parents and siblings are and what not. But do you believe in destiny? I mean really, if there was such a thing, did God create an imperfect being on purpose? If He knew us before we were born, does He know who will be saved or damned? Did He know that Adam and Eve would be decieved and eat from the tree? Thoughts? Opinions?
