So often Hollywood has disability as the origin story for the villains. Having a disability does not make someone into a villain, that is a negative stereotype that needs to stop being perpetuated by movies. 

Lindsey Row-Heyveld notes, for instance, "that villainous pirates are scraggly, wizened, and inevitably kitted out with a peg leg, eye patch, or hook hand whereas heroic pirates look like Johnny Depp's Jack Sparrow." The disability of the villain is meant to separate them from the average viewer and dehumanize the antagonist. As a result, stigma forms surrounding the disability and the individuals that live with it."
