> I am a strong believer in free will and it's what makes us so different than animals. Animals have instincts and very little free will.

Let me give you a friendly advice. Belief in free will has a purpose on it's own, just like belief in God. But if you choose to believe, stay away from attempts to explain it scientifically. You will only waste everyone's time and energy. Just assume free will as a fact and move on.

And keep animals out of it. They have as much free will as you.

As if science wasn't a belief system as well. As long as the source of your ideas is observation (as in all sciences) you have nothing but belief.

The advantage of science isn't that it can proof stuff (which it can't) but that it is open for change instead of being dogmatic.

Actually, the advantage of science is that it can predict the future in an accurate fashion.

Ergo: I know x will happen because when all the variables are the same in the past, x has always happened.

The accuracy of the prediction is what changes in science, which is why it is a better system to use for predicting future events than other dogma based systems.

Ergo: Recently discovered factor y can be changed as a variable, and this accounts for x sometimes not happening the same way. We must account for this as a variable too.

>> but it depends on the person

And what makes the person? A Person is an amalgamation of inherited genes and collated personal experiences. Most of the personal experiences are a direct result of your location.

I think it is very important for us to go easy on someone who has gone astray or in our opinion is not living a life the way we think it is ought to be lived.

A Person who is a firm believer in free will would not judge anyone or for that matter force his/her view on anyone else.
