You should expand on what you mean, but as from what I can tell you are asking if people have ever resorted to eating babies - I'm sure it's happened. I also know that during WW2 some places were so desperate for food that small children were "hunted".
If I knew where someone was eating a baby I'd have to go there and make them into a meal to show them it wasn't nice to eat babies. But I don't think people really would do that. Unless u say abortion is cannibalism.
