Why Do We Get So Much Joy Out Of Beating One Another?

Probably some instinct that evolved over time. 

I play poker for virtual money. I am almost a billionaire. There are people with trillions, so I am sort of poor.

When I catch someone bluffing, or play slow and fool someone, it makes really my day! I laugh, smile, chuckle. 

American football, soccer, basketball, other sports. People go crazy. 

Seems like we should be evolving out of such behavior. From a certain perspective, it seems very mean.

Vibrations in Physics

Various theories in physics stipulate that an infinitely small string or point vibrates and creates all things physical. 

In my mind, if you vibrate a point or string at certain frequencies, you get symmetrical patterns. In the physical world, not everything is symmetrical. 

So the vibration must be asymmetrical and still impart constructive information. Sounds like we are in a simulation? Could be. I was undecided before.
