There is no war between good and evil. There is no such thing as absolute good or absolute evil. Depending on what a person is going through depends on their actions. Humans as a whole are selfish but some are more selfish than others. Depending on a persons situation at home depends on what would happen if they saw a wallet on the ground. And it doesn't make you good or bad it make you human. If you take the money rather than returning it that makes you no more evil than the person that would have returned it .
