Life is a survival game.
When a company is going to lay off people, employees will try to save their own asses and step down on the people they call friends. In a project, if you are a boss, you have to learn to fire people who who don't do a good job because you are also under your boss. Even kids, they learn early in life about competition. Kids are divided into two groups. I guess the game producers are quite creative in that they've designed the game that brings out the worst in you.
