Yoshiiki is basically Lennenkanpt at this point.
I don't have such manly mustache.
Also it victimises the next of kin
Even if you dont consider the body to have rights, it technically belongs to the next of kin for burial/cremation purposes
Similarly, if someone fucks your toaster, chair, or a drinking glass you own without your consent, that's also a crime
Yeah, I thought of this variant too, but it can be exploited by question itself. If you do something to a person, that one is the victim, not their family. Problem with that analogy is reasoning in same manner as things, which can be turned into monetary compensation and while owner got victimized, there was no harm done to the person itself. So with that approach, technically there is no victim and that's what this question is based on.
Or to put it simply: Things don't have rights. That's why body having some rights by proxy of being alive earlier is a better idea, as we don't dehumanize as much and don't turn it into an object. So therefore, it can be a victim just like animals can be victims of animal cruelty while not being able to speak for themselves (and there are ways to determine if something was done to an animal).
With objects there is a lot of moral talking (like non monetary value), so I simply dropped an idea since I could easily refute it myself.
