I can't help but think of that episode of Star Trek: TNG where the woman comes to the planet claiming to be the "God" they all believed in. Why must a God be "good" and fair and just? Why should we have to obey the God just because they made us or have some power to decide where we go after we die, where our soul goes? That is morality based on fear, believing that you should do the right thing to ensure that you get in this higher power's favor to avoid the negative afterlife.
You are proving the point actually by talking about someone using force against someone else to try to get them to see their way. That is force trying to change another person's "beliefs" (which likely wouldn't work, after all, do you think you would change your mind about their beliefs if they started throwing those who believed like you off buildings?).
