The implication from the 1 Corinthians 12:22 passage is not that those in the Body of Christ who seem stronger are violent or evil as in the movie. However, there is a wrong being perpetuated. The wrong is seen in people with power prohibiting others who are gifted such that they are Biblically described as indispensable, from expressing that gifting by refusing to change.
The parts "seem" weaker, implying that those with power have relegated others to the category of being weaker. As a result, the Body of Christ as a whole, truly does suffer in this way, when one part suffers (1 Corinthians 12:26). The strong are haughty and the seemingly weak are excluded. Exclusion of people with disabilities leading to this type of attitude is much too common in the Christian church and we suffer as a result of it.
