I second your opinion of Heroes. I have become sorely disappointed with the series. It seems that after the writers returned from their strike, they decided to create TV scripts that appeal to the most subdued intellect, not only for Heroes but for almost the entirety of American television.

The robot probably isn't far off...

The Aztecs had a long legacy of cannibalism as part of their religious ceremonies. It was considered (I assume by those not experiencing it) an honor to be killed and eaten as a token to their god(s).

After the Spanish came and forcefully converted the native American survivors to Roman Catholocism, the Aztecs adopted the stigma attached to cannibalism. However, they couldn't get enough of that porcine protein brought over from Europe. When asked about their focused consumption of pigs, the former people eaters replied with a simple answer: pigs taste like you and me.
