Depends what you mean by free will. Some have argued that the ability to choose between different options in any real sense is illusory, but that a weak free-will is possible: If I had toast and marmalade for breakfast this morning, I may think that I could have had toast and honey, or a couple of boiled eggs, instead, but in fact I was predestined to have toast and marmalade - which doesn't alter the faqct that it was my choice. Whether that is enough to preserve moral responsibility is another question.
"Some", I repeat, "have argued": I'm not arguing it. Thinking philosophically about free-will and determination does my head in, so I just tend to go with Dr Johnson: "Our wills are free, and there's an end on't".
