"Eye" is the second story after Wesley's "Return from Space". It is strange and inexplicable, and it has a frightening feature among all Wesley's fantasy stories.The story assumes that the people on Earth suffered an alien invasion several years ago.The aliens are inexplicably evil, and the earthlings became immigrants of the aliens without any resistance, and started the evil civilization of the earthlings. The tone of the whole story, disappointment with human nature - this is the consistent theme of Wesley's fantasy stories, people are too sinful, sinful to a terrible degree.Although there are only a few people who turn evil thoughts into evil actions, most people have no way to deal with the few criminals. Why?Do most people who don't commit crimes have criminal thoughts in the same way?

"I was born in sin, and I was sinful when my mother conceived"—that is a poem that thoroughly understands the sinful nature of human beings, written by the second king of Israel, David, in BC It was written down more than a thousand years ago, and people have known it for a long time, but they have no intention of correcting it. Evil can only be eradicated after one has fully recognized one's own sin.
