Hmm “murder” is usually a legal term but I think a lot of people believe in justified killing in a lot of cases. Usually in a movie or game the character is put into a narrative or context where it’s okay or understandable for them to kill. Even in cases where the character is supposed to be evil and depraved the story teller is kind of playing off the viewer or player’s preconceived assumption that, for example, killing innocents is wrong.

Serving someone what looks like a cut of beef (but really isn’t) doesn’t similarly problematize the product with context like storytellers usually do in games and other stories. It’s simply mimicking the real thing. Maybe a vegan restaurant with gory peta imagery would be a good comparison to how we might problematize meat subs similar to how storytellers recognize the depravity of killing in their creations while still including killing.

A game or movie that included rape or reasonless murder in a fully positive context/narrative would either be art or really bad taste.
