Help Finding Appropriate Song For This Video? (:?

I have to make an imovie on the Holocaust & I picked the topic of Adolf Hitler. My movie is going to be about his life & how horrible of a person he was. The problem is, I cant find any songs that would represent this imovie approriately. Can someone please give me a list of suggested songs.....i was thinking "Jar of Hearts" by Christina Perri , because of the chorus. But the song is more about love & sadness after a breakup , not about a man who murdered tons of people. Help..?!
