What have we become?

Mayeb not us few, but mankind in general. I feel man is like a self degerenative program. We create all these rules and boundries just so another half of us breaks them. And then we fight this war with ourselfs and others. Hate, evil, mistrust, apathy, vengence. Why do we cause this upon others? A close friend just had a 2 foot long key scratch put into her car. So hard in fact that it went right through the sheet metal. Everyone please play nice and be nice to on another, please.
