Jesus became subordinate to the will of the Father.
If he really had free will, Big Daddy would have cut
him loose from crucifixion when Jesus asked that
cup be passed on from him.
You left out "if it be possible." In other words, Jesus chose to adopt his Father's will as his own, regardless of what his human nature might have been pushing him towards. It's human nature to prefer not to suffer. Nevertheless, even crucified, he could have asked his Father, and he would have commanded more than twelve legions of angels to destroy the Empire and bring him off the cross. Their wills were, however, as one on the matter of the Crucifixion. This was why he came into the world.
