Kurt tries not to see things from a black and white perspective because he knows he could be bound to hurt an innocent being! Because of Kurts harsh childhood he sees corruption when it comes to law, for example if there is a whole bunch of starving villagers he would take matters into his own hands saying: " if you are not going to help them, then someone has to!" If helping the poor is what breaks a law then he enjoys being a "criminal".
The type of hero he chooses to be is the man who's here to bring service only for cause!__
