Anyway, imagine what you would do in that type of world I was talking about. You can go to your worst teachers and jack their resources, then blow off their heads if they get infected or become a zombie. The government would have no control, even paper cuts or getting cut by a knife chopping vegetables can be lethal because the medical supply would be low, so people would simply die off from infection. You can restart society. The government wouldn't have power, only those that have the most food and resources would be able to control the masses.
Ooh, and then there's the occult. Almost every time disaster struck, humanity turned to religion or some kind of belief. Imagine you could utilize their faith and their state of psychological turmoil to create your own army, that would kill in the name of whatever theology you make up. The world would change dramatically, you would be able to do whatever the bondages of law and order wouldn't let you do before. You have chaos, and you can mold it to survive, and control others in the promise of survival.
Plus you get to gather up a bunch of your friends and slay some bitch ass zombies.
