Just a guard? If he is proven to have been a guard at a death camp then that means that he ACTIVELY AIDED in mass killings. Any guard there would have known EXACTLY what was happening and still chosen to come to work every day. **** him. War criminals differ from regular criminals in that they can usually hope to get away with their actions. If their side wins the war, then it's not going to be considered a crime. Even if their side loses, it's usually pretty easy for them to change identities, or hope that their actions are obscured by the fog of war. Because of this, it becomes even more important to deter future war criminals with the knowledge that they will be hounded to the end of their days; that there is no statute of limitations. The sight of this pathetic old man rotting away in prison is something important to show.
