Well that mindset is Darwinism in action. I would also describe it as pure, unadulterated, generational complacency and laziness. Bush village life doesn't need to include offering yourself up as an hors d'oeuvres. But if that's what they choose then so be it. I just wish the kids weren't the victims of it. Unfortunately, they are just a link in the chain. Like you said, most of Africa is a different mindset.
I'm also not sure what living in an air conditioned house with running water over here has to do with it as plenty of your local simple thinking villagers would agree with leslie. Actually most would be more vengeful as Pete pointed out. I could live in a cardboard box and realize that sitting at the edge of croc infested waters is a bad idea. Personally, I don't think the crocs deserve to die because of such actions. They're simple minds and eat what is handy at the edge of their domain. Don't be the thing that is handy.
