During the second world war, Deutsche Bank was engaged in basically taking over the banks of conquered territories and there was at that time a wealth of enterprise, factories and properties that were confiscated by the German State, the financing of many of them became the responsibility of Deutsche Bank. One of the other things Deutsche Bank achieved during the war was to finance the development of former Polish Military Barracks called Auschwitz, and also many of the German businesses that used slave labor. So what with one thing and another, following the Second World War the occupying powers divided Deutsche bank into ten separate banks. Inevitably what remained of Deutsche Bank developed a culture very much of its own, and a part of that culture is more prone than most banks to fish for profit in those areas other banks wouldn't touch with a cleft stick.
