It's almost a universal for people who live around the ruins of an older society to attribute that society's downfall to some kind of sin.

The Navajos have a Soddom and Ghomorra tradition about the Anasazi.

THe Welsh had such traditions about the downfall of Roman Britain.

The Greeks accused the Minoans of hubris (hence the legend of Atlantis.)

The Jews accused themselves of sin again, and again, and again, every time an outside force came to their borders. Both exiles are attributed to corruption and sin.

Can you link me to any information you know about the Navajo thing? I'm pretty well versed in the area, but I'm not aware of anything like that. It's also worth noting that "Anasazi" is considered a bit offensive by modern puebloans. Ancestral puebloans is preferred by archeologists, but that could be interpreted as a political stance depending on who you are.
