There are no limits to cruelty, savagery and treachery:

• Liput (Manobo, Philippines): to throw someone off guard.
• Usauara (Yamana, Chile): to shout, as a group of men, when ready to make an assault on someone they intend to kill.
• Ahaneoha’ov (Cheyenne, USA): to kill someone by stepping on him.
• Tsantsa (Jivaro, Ecuador): a human head shrunken and dried as a war trophy.
• Tzompantli (Aztec): a rack of skulls.
