I'd do the same thing-Have you played atwar? It's a game where you take over countries, and you can ally up. To betray friends and join the enemy is a good move sometimes, and it should be done in secret.The end result? You get the most points, and you win faster.
Yeah, it is.Hell, don't even look back to the Romans, look at the last 100 years.
I'm trying to approach this issue in a story I'm writing. I'm interested in the way societies perpetuate struggle through history, and how individuals are influenced in gradients to carry out its will against their better judgment.
