How does Paz explain the suicides of the Aztec people? Is it a reasonable explanation?

Paz explains the mass suicide of the Aztec people by tying the event into both vertigo and despair. The vertigo, he says, resulted from a perverse admiration of the Spaniards; and the despair from the knowledge that their great kingdom was ending. The Aztec nation, that was new and still maturing, also would have been subjected to the fascination of death, which was common to young people (Chapter Five, page 94). Noon and midnight are the times when young people are most drawn to death; the Aztecs looked up at the sun and saw death written there. Paz's explanation of the suicides of the Aztec people is reasonable because it takes into account both the high and the low emotions that the people must have been feeling. It is unusual too, but surely encompasses the multiplicity and complexity of the thoughts that the people were wrestling with at the time.
