When focusing on disability in the play like blindness and madness, this scene I think Shakespeare treats as a sane event. The servant, unlike other characters in the book, actually see what is happening to Gloucester and they fight for him because of how mad Cornwall’s actions are. Throughout this scene we also see the servants hesitant to jump in and get involved in the situation but I think Shakespeare does that to mirror the audience and to show that if you truly cared and truly saw madness this is what you might do as normal people.
