What is Eliezer Wsisel's moral?

I really don't think of stories like Elie Wiesel's novel in terms of morals rather than themes. If I had to put a moral on this, I might consider "never giving up". It would have been so easy to lay down and die, to just end it all instead of going through that hell. As for examples, they are all through the book. From the hellish transport in box cars to the stench of burning flesh in the air, Elie had plenty of reasons to give up.
