Well the question to me is HOW do they actually know that they are the last people on earth??? Was there a sign that said "If you read this, you are the last of us. Signed: Mankind"?

Well I think they hadn't death penalties in the beginning. They killed themselves, so they made up all the rules for the second group.

Well, Pope was not white…
