If people chose to ignore the message. They will have to deal with the consequences of their choice, namely becoming infected themselves.

As for the champions, they or your avatar, jimmycrackcorn, oldmcdonald all have equal chances of saving humanity or becoming infected and being the harbingers of doom. They are like Parzival in RP1 First to the Key. He was no more special than any other player, just the first. The video guy will be back, he ain't dead he also may use another face next time. He will say anything to get people to do what he wants them to do. Next time he might refer to your character as the Savior. He may take send someone on a mission with the express intent of knocking them down a peg or two if they get to uppity. Whatever gets the job done he will do it, even if it means ensuring someone is set up to become infected.
