depends on a lot of factors but mainly the nature of the person going through the hardship will decide this.

A negative and pessimistic person will probably be pushed further into pessimism and be more greedy viewing everything through a dark colored set of glasses.

A person who is typically thankful will see things differently and remember all the people that helped them, after they do get through the hardship and will usually be a lot more empathetic toward others in need going forward.

That's rather simplistic and there are many other factors but it's kind of the base. The same as prosperity can affect people in opposite ways too.
