5. A live human, or animal, used as a sacrifice or in a religious rite.
6. Etymology: "a living creature killed and offered as a sacrifice to a deity or supernatural power"; borrowed from Middle French victime, and directly from Latin victima, "person" or "animal killed as a sacrifice", or "any sacrifice".
It might be distantly connected to Old English wig, "idol" with the notion of "a consecrated animal".
The meaning of "a person who is hurt, tortured, or killed by someone" is first recorded in 1660; while the meaning of "a person oppressed by some power or situation" is from 1718. The weaker sense of "a person taken advantage of" is recorded from 1781.
