I just watched the boy in the striped pajamas and...?

Im so upset its unbelieveable. I cant stop crying, Im sad and mad, they are SO evil. While watching this I was so upset i pulled at my hair, and scratched my face. I dont think Im going to stop crying all night. I cant believe this happened to innocent people. Bruno's innocence and love towards his friend touched me. I cant describe the things that are going through my head right now. Why were they so cruel?
