Mad Doctors and The Debt

Mad Doctors have long held a fascination with most people. From their complex, often uncompromising natures to their ability to bend the rules for their personal gain, or risk everything anyone else would hold near in pursuit of some idea.
In the Debt,  Dr.  Dieter Vogel a Nazi Doctor referred to as the Surgeon of Birkenau set up a practice in Berlin after he escaped the war. He managed to eluded officials for years and to the casual observer seems like a poster child for rehabilitation, but his also all too ready to jump back on "the nazi bandwagon if it ever rolls into town".
As a result Dr. Vogel is a complex character, which makes it is easy and tempting to write him off as a psychopath. We often do this because we probably do not have an explanation as to how an intelligent, upstanding person could be capable of such atrocities, stooping down to such a low level. After all crime is usually associated and  reserved for the poverty stricken populous.
This shows how we have come to define people according to how much money they earn and their social standing - a belief propagated by the thought that if someone has money they are well adjusted and what more could they ever need from the world they are comfortable. And that criminal activities only exist among the poor. Mad doctors force us to reevaluate our beliefs about intelligence and good standing.
Knowledge is power and with that power comes a great responsibility to hold on to one's moral compass, so that the individual can remain grounded.  Once this moral compass is lost, the individual becomes drunk with power and since they have not only knowledge they now have the capacity to manipulate situations and people in their favor and for their own benefit, which is almost always catastrophic.
