Humans can try and force or dictate the will of others, but remember, NO human can alter a human's inner will or state of mind.
For example, I am a slave, and my slave master can beat me and whip me and force me to do all his work, the master can separate me from my family, and put me through tiresome troubles and hard labor. The master will always say that we slaves are not even human, and that we are meant to be serving the rich, and this master will always keep telling me that I am nothing, that I am supposed to be a slave etc etc.
But the master can NEVER change my OWN will, that I AM a human, and that I DESERVE to be a free man etc etc.
Another example, a person can FORCE another person to accept a specific religion, but that person who is being forced to accept that religion, he may physically accept it, but MENTALLY and SPIRITUALLY, they DENY that religion.
So humans only have power over your body, but do not have power over your spirit. This type of stuff still exists today, no denying it.
Remember, Free Will comes in many forms, our freedom can come in our actions, the way we act, you know, or the way we think, the way we speak, the way we worship, the way we feel towards other people and things.
Evil humans can try and force humans to try and do something, but they will never succeed, and God will punish them for doing this in the after life.
