The Free Will
I believe free will is nothing more than a fabrication of the human condition. It is an illusion that we accept because we cannot observe all the process that are involved in making a "choice". I believe in science. So far, all proven theories, (that is theories that can tie actions we have witnessed to there fundamental properties) point to the realisation that all actions in the universe can be broken down to basic laws and actions. I'm not implying that we understand all of these basic laws, but it seems logical to me, that all things are composed of numerous complex reactions (from what has been observed).
Therefore we can infer that all human actions are our primal actions (genes) interpreting and acting our surroundings. Now, this may seem unlikely or even absurd, but the only reason we perceive it that way, is due to our lack of understanding in the numerous process present within the action of human thought. The actions we react to themselves are determined by rules, so it can be inferred that the interpretation of these actions can only occur in one way, the way they occur, and so it would appear as if we all are tied by this predetermined "fate" of action reaction.
In conclusion, human error does not exist we only act in the way we do, and that is the only way we can act.
