Some people talk about good and evil. There are good people, they say, and there are evil people. Those who say this, of course, are good. Others are evil.
Actually, evil is in the eye of the beholder. The beholder sees evil and looks for evidence of evil. If they seek, they will find. If somebody says something with which they strongly disagree, they call him evil. If somebody believes in a religion, philosophy or political ideology with which they disagree, they call her evil. If someone has the wrong kind of glint in his eye, they call him evil.
