I am inside of most living things. I am balance, I am karma. I am the countrweight and I also tip the scales. I am the cause of wars, and I am the inspiration for a witty retort. My wife is pride; my best friend vainity. You can see me in the local club fights and the shootouts. I am council to problems in the Middle East.

I hate the peace so I start the wars. I am what makes men kill their unfaithful wives and I am the reason they cheat. I am an endless cycle. I am more addictive than heroin, and much less than half the price. Not many can figure out how to detach themselves from me, especially those without faith or humility. What am I?
