In some parts of the world, people DO celebrate death. They see it as a party and celebration to move on to another level of being. I suggest you stop playing videogames and learn a little about the world.
You people are making fun of our little Virtual Villagers "tribes"? American arrogance is proven with you who believe western culture is superior. Ancient tribal beliefs that are still practiced are idiotic?
Step away from the computer, turn on the Nat'l Geographic channel and maybe you'll see that in some parts of the world, the culture is different. Their beliefs don't make them any less of a vital culture than the one you're a part of. Grow up. Read a book.
