In Agatha Cristie's And then there were none, how does she use suspence to further the plot?

Oh, my! Have you read this story?

Killing off the people one-by-one involves the reader and creates suspense as the reader knows that another character will be killed. Who is murdering these people?

what moral lessons is she pointing out to the reader?

Think about why the murders are committed. What moral lessons do you think Dame Agatha is pointing out?

the murders were committed to see if they could be done.. just like many other stories where the curiousity of getting away with it leads you to kill..

I suggest you go back and read it again. You've missed the point.
