Ghandi said it is import to remember we all have our own Hitler inside of us. We have to be constantly aware of the dark side of our human nature. I think it is healthy for you to ask questions about this quality in yourself. You are trying to understand this and become more aware of your behavior. As human beings we all have the potential to be violent and harm others. We can never forget the dark side of our nature we have to learn to be aware of it instead of denying it or repressing it. When we deny it or repress it tragedy occurs. I appreciate your post. It makes me aware of my own darkness.
