For example, the people in Andale probably eat 10 people per year each, which would mean that they'd have to catch and kill someone every few days just to stay alive. The Raiders, too- there's tons of them, and they've probably killed at least one person on average. Every mercenary has probably also killed before.
The Brotherhood of Steel. One of them dies every minute or so that they're fighting, even if it's just in the Arlington Library or on the Mall. The Family, they'd have to kill SO MANY PEOPLE to live off blood. Mr. Tenpenny, he kills stuff all day from his balcony.
It just seems to me, that if everyone went around killing people all the time, there wouldn't be enough kids to grow up and have more kids, and there wouldn't be enough advlts to make those kids. So the entire wasteland should be empty by now.
Has this struck anybody else as strange?
