Good and evil are just so relative. You have to be able to enter in each head and wear everyone's shoes to really understand all the reasons, backgrounds and beliefs that moves every single person to act the way they do... Yes, It's complicated, and all I can suggest is to focus on YOU... you are you and , in this crazy world, you are in control of you (luckily) and your attitude , begin with that. ^^

Ironically, while the technology is more and more advanced, the very basic things like the respect between ourselves are being forgotten nowadays. Thats the main point. The second is the human greed. With a minimum, just a minimum percentage of the money expended to develop weapons and make wars, they could eliminate the world's hunger...thats the most evident representation of the evilness.

If you think about it, there isn't good or evil. Nowadays, the people in charge of the government defines what is "good" and what is "evil." Good and evil is just something based on what we believe. For example some people say war is evil others say war is a good thing. It all depends on viewpoints.

there is no clear line between good and evil.just as a coin has two side,there's no exception of human beings.
