1. As Rodya analyzes Luzhin's character, he realizes that the intellect not limited by moral purpose is dangerous due to the fact that many astute people manage to see past that false facade. Luzhin's false facade of intellect does not fool Rodya or Razumikhin, and although they try to convince Dunya not to marry Luzhin, she does not listen. Rodya believes that Luzhin's "moral purpose" is "to marry an honest girl... who has experienced hardship" (36). The only way he gets Dunya to agree to marry him is to act as if she is a very intellectual person, who is actually not as educated as she says she is. This illustrates the fact that Rodya knows that it is really dangerous because he knows that people can ruin their lives by acting like someone they are not. Rodya also knows that people isolate themselves from others precisely so that no one discovers their true personality. This is illustrated by the fact that Luzhin tries to avoid Dunya and her mother as much as possible. The way he writes his letter exemplifies his isolation, because Luzhin does not know how to interact with society. He has no idea how to write letters to his girlfriend and his future mother-in-law. This is reflected in Rodya's second dream because he is unable to get Dunya married to a good person. He feels isolated from everyone else because his intellect has made him understand that Luzhin is not telling the truth about his personality. However, it is because of his lack of moral purpose that Rodya berates his sister's boyfriend. He cannot control himself and due to his immoral act of getting drunk, Rodya loses all judgment and therefore goes and belittles Luzhin. Even though Rodya's intellectual mind had taken over and shown him that Luzhin was... halfway... losing the will to live; then Rodya was no longer able to bear the pain and killed Alyona. After this interview, Rodya had his third dream in which, no matter what he did, he was unable to kill Alyona, who laughed hysterically at him. Due to his inability to kill Alyona, he loses all his intellect and becomes like a mad beast trying to kill Alyona. It also symbolizes the fact that no matter what happens, Rodya will never be able to get rid of the pain and torture that Alyona put Rodya through and with this, the idea of ​​her will always be there with him. This exemplifies why he cannot “kill” the “old witch” because he can never forget the pain he put his debtors through. He can't kill his witch and no matter what he does, no matter how much intellect he loses, he can never be rid of her and she will always haunt his memories and dreams..
