RAEL’S COMMENT:
The word holocaust means the sacrifice of an animal to honor a god. So it’s totally not adapted. Shoah (catastrophe) is more acceptable.
A holocaust is a religious animal sacrifice that is completely consumed by fire. The word derives from the Ancient Greek holocaustos (ὁλόκαυστος from ὅλος “whole” and καυστός “burnt”), which is used solely for one of the major forms of sacrifice.
