Final answer:
The question regarding Cory not wanting to go to Troy's funeral cannot be answered based on the provided texts, as there is no clear link or context between the characters Cory and Troy or a related funeral scenario within the snippets given.
Step-by-step explanation:
The question "Why does Cory not want to go to Troy's funeral?" seems to be based on a confusion between two different literary texts and characters, as the provided text references Marcus and McTeague from Frank Norris's novel 'McTeague', and a snippet from the poem 'Richard Cory' by Edwin Arlington Robinson.
Neither of these texts provide any clear link or context to Cory or Troy, or a funeral scenario related to these names. Therefore, without additional context or a clear reference to a specific text where both characters Cory and Troy exist with a defined relationship, it is impossible to give an accurate explanation for the motivations behind the character Cory not wanting to attend Troy's funeral.
If the question pertains to a different literary work not included in the provided references, additional context would be necessary to adequately respond to the question.
Cory does not want to go to Troy's funeral because he believes that attending the funeral would be a way of accepting and condoning the way Troy lived his life. Cory and Troy had a strained relationship, and Cory felt betrayed by his father's actions. Cory sees attending the funeral as a form of hypocrisy, and he chooses to distance himself from the event.
