How does ivan ilyich perspective towards death change over the course of the novel?

Ivan Ilyich lives a carefree life that is "most simple and most ordinary and therefore most terrible". Like everyone he knows, he spends his life climbing the social ladder. Enduring marriage to a woman whom he often finds too demanding, he works his way up to be a magistrate, thanks to the influence he has over a friend who has just been promoted, focusing more on his work as his family life becomes less tolerable.
