What is good behavior and what is bad behavior? The nazis had an ideology that told them that to commit the acts they did was good. And when a woman is stoned, the people doing it consider it good. When witches were burned, the people that did it considered it good. And the same people would consider it bad to do anything else. So it has a lot to do with ideology, politics, values and sometimes religion. I think we have to first think about how do we define good and how do we define bad. These examples might seem far fetched, but the world is stilll like this today. Some people will consider it good to do things I would consider very wrong. And some people are just plain psychopats.
