After reading A Problem from Hell, I am much more knowledgable in the topic of genocides that occured during the twentieth century.  Although many history books may be boring and not interesting, this one is definitely not.  Samantha Power is an amazing author and I was fascinated while reading her book.  I now see the relation of evil and genocide much better.  It is inexplicable that after many countries vowed that genocide would never occur again, it did many times after.  The evil that occurs when millions of people are murdered is very great.  I cannot imagine the type of person who could order such a thing to happen.  Genocide is indeed evil.
