Why was Chief even institutionalized in the first place?
I just don't understand why he was in a mental institution at all. One realizes throughout the film, that he is a perfectly functional and rational human being, just like McMurphy, who has no real reason or right to be even there in the first place.
So, why he is even there at all, pretending to be a mental patient, really escapes my wits. Pretending to be deaf and mute (supposedly to avoid interaction with the nutjobs in the ward) does make little sense to me as well, because those physical disorders are not a justification to be in an institution, nor are an advisable way to deal with mental people, because it is extremely difficult to pull that off. He could have gotten rid of them simply by being assertive, even more so because of his size and intimidating looks.
So, if anyone read the novel, can you please tell me WHY he was even a patient there, in the first place? Because, by watching the movie, I just couldn't find out any explanation for that situation.
