the evil of banality
It seems that a lot of people feel they can judge the goodness of another person by looking at them. That process almost always yields condemnations of villainy based on things like skin color, mode of attire, hair style, personal hygiene, and a number of other factors that many harbor a sense of "ickiness" about.
If only it were so easy. It is time for humanity to realize that the biggest evil is that which is the best disguised.
This is the real face of evil. Smiling, grandfatherly, non-threatening, clean, well-groomed, and able to cut your throat without changing demeanor.
