Free Will
Free will is a way for us to determine a course of action to each decision that lies before us. It can be thought of as a choice one makes in any given situation. We, as souvereign human beings, are allowed to dictate in which direction we head, or which option we agree to. No one is really allowed to make decisions for you. You have to agree or disagree with them.
We can have someone else make the decisions for us, if we so choose. Normally this is done through Power of Attorney. This is normally allowed if the person is incapacitated for some reason, and does not have the full capacity to understand things any other person would. But other than that, the decision making should be ours, and ours alone.
Man often times, as he does, make decisions without our knowledge. We have seen this repeated all throughout history. It was never meant to be that way. Like all things, there is duality in this 3D world. There is an opposite reaction to every action taken. And that reaction will affect others, since we are all connected spiritually. If free will is taken away, then I suppose that the Creator's judgment will ultimately come into action against the perpetrator, in some form.
