Notice that in the picture the victim is not an evil white Spanish conquistador, but a person of color.
Even though, they were heathens and savages by definition. You maybe not call them that today. Not PC.
The Aztecs took the opportunity to sacrifice a few conquistadors as well. According to contemporary accounts, during the battle for Tenochtitlan, groups of Aztec warriors would rush the Spanish line for the sole purpose of dragging back a conquistador and sacrificing him right in front of his horrified fellows. This had the effect of either making them think about retreating, or fighting all the more fiercely.
