Applying the entire situation to myself, I'm not sure I'd do anything all that interesting either. While it's nice to believe that this might actually spur me on to initiate a bloody rampage where I would mow down the seeds of humanity like sheep, I'm pretty sure laziness and apathy would stay my hand. I mean, it's one thing if the hoards of humanity were willing to make a housecall so I could sit in a comfy chair and mow them down with a machine gun with the tv on, but I'm not sure it's worth it if I have to go out there and find them while lugging my hardware. Just think about how much those ammo belts and clips must weigh after a while.
Oh well.
