Wuthering Heights by Emily Bronte includes the struggle for happiness, such as marriage, and revenge. Heathcliff grew up neglected and abused. When he fell in love with his longtime friend, Catherine Earnshaw, she betrayed him by choosing another man over him, causing Heathcliff to become bitter and unkind to everyone who came into contact with him. He goes out of his way to make everyone miserable and miserable just like him. Although Heathcliff's outlook is seen as "a mad man", he actually suffers from antisocial personality disorder, conduct disorder, and depression. An adult suffering from antisocial disorder normally begins with conduct disorder as a child. Children with CD (conduct disorder) are found when the child has a history of "repetitive and persistent pattern of behavior in which the fundamental rights of others or major age-appropriate social norms are violated, as manifested by the presence of three (or more) of the following criteria in the last twelve months, with at least one criterion present in the last six months." These criteria include aggression towards all living things, such as people and animals, defacement of property, cheating and thief, and failure to follow the rules. Conduct disorder is based on three levels: mild, moderate and severe. Mild cases are people who lie, skip school, and stay out late without consent. Children aged 10 and over must have at least one of the symptoms that make up celiac disease; they would therefore be classified in the mild phase since their symptom is deception and theft. The moderate form of this disorder includes theft and defacement of property. Severe CD is when a person acts out or deeply considers rape, abuse, theft, vandalism... middle of paper... employment and/or education. In the 40s there are problems with his reality or communication with some serious problems with his work, school, family, judgment, thinking or behavior. The 30s where behavior is influenced by hallucinations or delusions. There may also be serious problems with communication or judgment, as well as difficulties functioning in all areas. Stage 20 represents minimal danger of harming yourself or others, failing to maintain personal hygiene, or compromising communication. Level 10 reaches the point of seriously injuring oneself or others, failing to maintain personal hygiene, or being suicidal with the expectation of death. If Heathcliff were diagnosed, he would be found to be close to 30. This number was given to him because he is becoming delusional, the main example being that he has started to believe that Catherine is haunting him..
