Human sacrifice refers to the act of offering human beings as a sacrifice to a deity or supernatural power. However, this term can be considered quite harsh and may not be appropriate in certain situations. Therefore, there are various synonyms that can be used in place of human sacrifice, such as ritual killing, offering, victimization, immolation, and execution. These terms convey a similar meaning while being less explicit in nature. Additionally, it is important to note that human sacrifice is an obsolete practice and has been outlawed in most societies. The term should only be used in a historical or academic context and not as a justification for any modern-day actions.
