Free will is a confusing issue. It seems to be one of those things where if you look at it one way, the answer is one thing. Change the way you look at it and it becomes something else. For example, I entirely believe that people make decisions, weigh pros and cons, analyze factors, etc. and make an informed decision. We do this all the time, and can learn to do it more effectively. And I don't believe that there is any supernatural agent that influences these beliefs in a way that eliminates control of the person.
But then, you can look at it considering all the factors that led to that decision, your raising, your ethics, morals, preferences. All these factors were the way they were, and were out of your control, and ultimately these factors that determined your choice did so in a way that you could never had altered. So maybe in hindsight, it looks like free will isn't completely under your control.
I would say on a pragmatic level, yes, we all make choices and we know this. There have been times when everyone has two or more choices and almost made one choice, but something made them decide to go a different way. People are obviously responsible for these choices, and always have been. That's just how we know things work and how we interact with the world. But I suppose if you want to get into some abstract, quantum, impractical look at free will, it isn't under your control completely, at least the way you define it. Me being a pragmatist, I recognize that at a given time, yes, I could decide to go left instead of right without any factor changing. Really, all you can do is hypothesize about whether or not it is actually a possiblity that my brain could have made the opposite desicion under the same circumstances.
