How does the universe itself play as a villain in "the guest", by albert camus?

I believe Showalter is alluding to the fact that if as individuals we do not make our own choices and decision we become slave to what the universe dictates rather than fulfilling our obligations to ourselves. In other words, if we need to make a decision, we'd better do it...... because if we don't have an active role in our own lives the universe will randomly choose for us.
