In the event that any of you become infected, how would you handle the situation? How long would you wait to tell someone, would you tell? Would you...eh...well, handle the situation yourself? Would you infect someone else?
I would cover up my bite and go to a heavily populated area and wait to turn into a zombie and bite everyone else. Its kind of the asshole thing to do but if i was already bitten then i would be playing for the zombie side and want them to win.
I would tell those around me first and foremost. I wouldn't kill myself because I could at least be helpful until the very moment I would turn. So, then, someone with a machete or other handy weapon could do it when the time would come.
Once infected with the virus i would use the time i had to dig my self a deep grave and fashion a way for me to destroy the brain while simultaniously allowing the grave to fill itself, how depends on what's available, the challange would be at least rewarding in itself.
I would make peace with my self and the world. Leave knowing i got a grave and some time, something a lot of people dont get the luxury of. If i was with a group I would have just left without saying a thing, a death would just de-motivate them.
