To say that he was pure evil and leave it at that would be, in my opinion, overly simplistic. Perhaps this is one reason why the authorities and law enforcers are finding it very difficult to find a motive and equally important, a method to his madness. You see, even the most evil men who have ever walked the planet committed evil deeds, even deeds so unimaginably horrific, take Adolf Hitler for example, because of the "good intentions" of there twisted belief system. Thus they must find out what he was truly passionate about and try to figure out whether and why he felt the need to kill himself and several others in order to attain it.
