It depends on your definition of free will. To me, the term implies that an individual is in full control of his own choices and holds all or most of the responsibility for their circumstances and actions. But I don't think it's quite that simple. Would you attribute full responsibility to a baby or a young child? Probably not; they're too young to understand the ramifications of their actions. Pretty much everything they know and how they act is dictated by their parents, so they have no say in the matter until much later. But why am I talking about children? Because we know for a fact how much childhood affects people for the rest of their lives. One can easily spend decades untangling the emotional mess left by poor experiences during childhood, after all.
The point I'm trying to get across is that much of who you are depends on things you have absolutely no control over. Not just childhood experiences; your environment and genetics also play important roles in shaping your personality, abilities, identity, and all sorts of important things. Of course, it doesn't mean we don't have any moral responsibility at all. If there is such a thing as free will, then the way to exercise it is through personal accountability. You may not be fully responsible for who you are or what you do, but you are accountable for it. You've been given a bad hand, but now you have to play it. The tab is on you.
