To revolt is a natural tendency of life. Even a worm turns against the foot that crushes it. The vitality and relative dignity of an animal can be measured by the intensity of its instinct to revolt. It follows: human dignity is measured by the intensity of its instinct to question.
If a JW excises this basic instinct, he is not only disfellowshipped but is eternally shunned.
Thus, creation proves JW system is wrong. What creation proves is necessarily of the will of the Creator.
