@kennethamy,
Can we clarify what "forced" means? Suppose you are a bank employee handling a large amount of cash when a robber bursts in. I would say the following:
1. If the robber snatches the cash out of your hands, or hypnotises you into handing it over to him, you are forced in a
physical sense; you literally have no choice.
2. If the robber orders you at gunpoint to hand over the cash, you are not forced in a physical sense (since you have the choice of refusing) but you are forced in a
legal sense (i.e. you have a good excuse, so you will not be punished). You act of your own will (choice), but not of your own
free will.
3. If you know the robber is unarmed and physically weaker than you, but you give him some cash just to make him go away and stop being a nuisance, then you are not
forced in any sense to give him the money, but you are
caused to do so. You act of your own
free will, and therefore do not have a good excuse for your action.
The boundary between force and non-force is not always clear-cut. For example, if I am in pain and take a painkiller, am I forced to do so? I think it depends how bad the pain is.
