Free will/evil/punishment

[Aroura]

Only if your fate allows such a recourse.

I think you've hit the nail on the head, at least for me.  It seems to me that if one's fate (by which I assume you mean determined outcome of a deterministic universe) has brought one into contact with the belief that free will is an illusion, then that person's behavior should be expected to change, if the idea is strongly believed.

However, I do not know of anyone who doesn't act as though they have free will.

And yet, you realize you have constrained will, yet you still act every day as if you have unconstrained free-will, because that is how humans are biologically wired to behave.

I can realize that it is just some hormones in my brain that are causing me to be depressed.  An amputee may realize it is that their hand is gone and it can't feel pain anymore yet still suffer phantom pain syndrome. In both cases just realizing the truth changes nothing about how our biology reacts.

However, in all the cases above, we can stop and think make long term changes to our behavior through other behavioral modifiers, like bio-feedback therapy.  The act of REALIZATION itself does not change much, but it opens the door to make changes in other ways. 
Does that make sense?
