How does shakespeare dramatize this theme in the excerpt from king lear

The 84th line in the sentence

''discuss the change or lack of change undergone by the main characters. in 1953 arthur miller wrote a play entitled the crucible, by writing this he aimed to challenge the assumptions of us society and led people to question each others responsibilities. in the 1950's senator joe mccarthy started to exploit the us fears of communism and organised a witch hunt. miller would have seen this as similar to the holocaust in the sense that people were being wrongly accused of being witches when they were not. arthur was a jew and so would have had sympathy with these people and this in my eyes was one of the key factors in the writing of this play. during the 17th century there was an outbreak in the belief of witchcraft in europe. this led to mass immigration from europe to america; the immigrants were puritans and so set up their own strict christian communities. this is how salem, massachusetts came into being. miller's characters convey my point through their change of personality from act i through to act iv. there are different types of change throughout the play such as change in character, beliefs and loyalty and these all occur at some point in the play to different characters."
