based on the
articles (links in Spanish) written by someone who spoke to the actual team that had to face down the Nazi dude and his team-mates, the reason he did that was not as some sort of scoring trick, but because he was in fact, a Nazi, who believed Nazi things and wanted to make it clear and blatant to everyone around him that he really, really loved genocide.
