And Jesus' rejection of Satan's simplistic answer means that he intends to help us. Second, if you can't control people, you have to approach them with respect. People are flexible, but they are also stubborn. People have free will. Ultimately, a person's heart is their own to give, and in order to give it they must have the freedom not to give it.
People do what they want, and no one can really benefit humankind by lording over people.
Ultimately, the greatest human leaders are people who respect other people and invite their respect. Instead of compelling our obedience and service, Jesus put himself forward in obedience to God and service to human beings. We must put ourselves out there for the sake of things we know to be true, before others go along with us or give us approval. All of a sudden, we find ourselves in the realm of the spirit and the realm of possibility. We can do many things we did not know we can do, and life changes because we take steps.
