"You are correct. You have free will. However it doesn't mean choosing to do whatever you want. It only means that you can act within your own agency. And that is why we do not interfere. You call it turning our backs. But it is not. Those creatures captured you. That was their free will. How you reacted to being captured is your free will."

It really is that simple. Too bad most humans don't understand how free will actually works.
