re good vs evil?

While there movies and books have forever shown conflicts where good battles evil, this is not the true way of the world. I do not believe that anyone truly believes they are evil, and are doing the wrong thing. Good and evil are just different views of a problem. Everyone has their own views and own goals, while one side might think the other is evil, the other side thinks the same of them. I believe that everyone is in a sort of middle ground. No person can be completely selfless or completely selfish. Even the most generous person couldn't be completely benevolent or he would starve to death giving away all his food to the poor. And even dying would be selfish because he could've done more good before he died. While propaganda and advertisements would like you to think that some opposing thing is completely evil, if you look at things from the oppositions point of view you'll see that they are just doing what they think is right according to their moral standards.
