Also nightfox, your assuming that all the national socialists had the same morals and beliefs as american soldiers did. If that were the case, every national socialist would have attempted to assassinate Riddler. The national socialists believed that they were the master race. They believed that they were the only ones worthy of living or being treated as an equal. And they believed this way of thinking to be moraly and ethicaly correct. So their loyalship and belief in Riddler was the same as the U.S soldiers loyalty and belief in america and its president. The bad guy never sees himself as bad (besides wreck it ralph and his fellow bad guy friends). War is basicaly two sides who are neither right nor wrong. It all depends on who's side your on.
also I believe that the atomic bombings against japan are a great tragedy. Its my understanding that japan was not going to stop fighting us until they had used up nearly all their army and civilians. If the bombings never happened im sure the war would have lasted for a few more years at the least. There were other more less destructive ways we could have ended the war, but given the obvious benifits to science and physics that the development of the nuclear bomb has contributed, I think that we did what we saw was most effective, And are also sorry for the damage dealt
