Don't you have a dictionary?
The real question is: do you?
The Mayans were not a primitive civilization. In many respects their astronomy and mathematical calendrical skills surpassed those in Europe at the same time. They were amazing civil engineers. Take a walk through Tikal sometime.
If you want to talk about brutality you'd better think carefully on such things as the Roman Circus and persecution of Christians; the Spanish Inquisition; the ancient Greek and Carthaginian treatment of unwanted babies (and ours today!); the Viking Berserkers ... the list is very long and unbelievably brutal. Oh yes, the Conquistadores' slaughter of the Aztecs and near-total destruction of their culture and civilization. I think I might have preferred to have my heart quickly ripped out in a Mayan fertility rite than to be one of Napoleon's poor soldiers dying slowly of cold and starvation in the Russian winter.
These passions and frailties are neither Mayan nor European: they're human. Get a little perspective.
