According to the Orthodox Study Bible you are incorrect.

Accoridng to the koine Greek language used to wriote the New Testament the word for sacrifice and victim is one and the same. Look up the word thusia (θυσια).

[Kolokotronis]

In modern Greek, the word for victim is θύμα; same root, same concept as θυσια, different word. In koine there is only the one word, θυσια, so far as I know.

It not about word smithing. It's all about context. Here are different ENGLISH interpretation of the meaning of "sacrifice/victim":

Sacrifice

1: an act of offering to a deity something precious; especially : the killing of a victim on an altar
2: something offered in sacrifice
3a : destruction or surrender of something for the sake of something else b : something given up or lost


Webster on sacrifice

Victim

1: a living being sacrificed to a deity or in the performance of a religious rite
2: one that is acted on and usually adversely affected by a force or agent : as
a (1) : one that is injured, destroyed, or sacrificed under any of various conditions (2) : one that is subjected to oppression, hardship, or mistreatment
b : one that is tricked or duped

Webster on Victim

You certainly would not change "the sacrifices made by parents" to "the victim made by parents" although many parents feel victimized at times. Nor would you say a "a frequent sacrifice of political attacks". Both usage would be silly in English. What is important is the context in which the word is used.

Christ was not a victim. Christ free gave himself as a sacrifice. None of the interpretations agree with the term "victim". Nor does Church history concur that Christ was a victim in context. (Not to mention the said passage was added as commentary.) While you might think that Greek is such a pure language, when translating into English there are nuances to terms.

Even the American Greek Orthodox versions uses the word "sacrifice". ;O)
