How are the endings of "Paul's Case" and "A Journey" ironic?

A.Money turns out to be everything for Paul, and the wife dies in an attempt to live.

B.Paul watches the train go by, and the wife finally reveals her husband's death.

C.Paul wants to meet his father, and the wife wants to see her family.

D.Paul feels guilty for stealing the money, and the wife is happy her husband died.

In "Paul's case" we see that Paul is only happy and content when he get his hands in a great amount of money he stole from the company he worked for. When he hears that his father has had to repay his debt and is coming to get him, he decides to take his own life, and rather than repenting from his choices, ironically, he can only think about all the luxuries he will miss out.

In "A Journey", we can see that the wife is so concerned about getting to her final destination that she hides her husband's death for several stations. However, after some time, she falls asleep next to his body, and when the train clerks try to wake her up upon arrival, she strikes her head against his dead husband's berth, and, ironically, dies before reaching her destination.
