The simplicity of evil

The simplicity of evil is so self-evident when you see it you must wonder why nobody else sees it. The latest photo shows a police officer nonchalantly using pepper spray on a group of students sitting with arms interlocked on the university of California, Davis campus. Can nobody see the evil of nonchalant violence on peaceful students? Or are we so numbed by police violence that we provide them the carte Blanche authority to do what they please in defense of law and order, security and oppression.
Evil must be in the eye of the beholder because not too many people see the US as a police state. However, not too many can see a child molester as a child molester either if he is a respected coach. Our society sees "greed as good" and "good as evil" so what does it take for one person to see the simplicity of evil? Most of the citizenry are so dehumanized that they see dehumanizing acts as normal behavior. The hope of future generations lie with the few who can see the simplicity of evil.
