Free Will is really big when it comes to philosophy (and religion). But I have to say that I am skeptical about it.
Here is the typical philosophical conversation:
"Why is there so much pain and suffering in the world?"
"Because we have free will, that is a gift given to us, and it is up to us to make the right choices."
I think this free will stuff might be an illusion. Let me explain why.
Free Will, by necessity means knowing all the facts about a situation. There is no free will if you don't know all the options.
Here is an example: (Pretty much a metaphor for life I would say)
You wake up in a labyrinth and you see lots of corridors you can go down. So you get up and start walking. There are plenty of corridors and you get to choose whichever one you want. But is that free will? Do you know what is down each corridor? Do you know the goal? Do you even know how you got there? Do you know what the goal is or where it is? Or if you even want it?
Nope, nope, nope, nope, nope and nope. You don't know any of these things. So how can it be free will that you are engaged in? You are making decisions based on nothing.
Heres the nutshell:
If I don't know how I got here, where I was before I got here, why I am here, or where I am going after I am here then where is the free will?
