The Hurt cycle.

I am getting a bit off topic here, but I just wanted to talk about one issue. Humans seem like self destructive creatures. Once one person has hurt one person, it is more likely that person will go on to hurt others. Either in physical way, or an emotional way. I like to think of this as the hurt cycle. I am a firm believer that once this cycle starts, it can never be stopped. I would even go as far to say that some people like to be hurt, but they would never admit it. The only way to get by in life is to make the best of it, and try and suppress the hurt. I think it is a rather dark viewpoint, but true in my mind none the less.
