consensual necrophilia?

Consensuality issue:
A sexual act with a corpse is generally considered socially unacceptable; the presumption being that the person would not have consented to the act while alive, it amounts to the rape of a dead person. Virtually all human societies condemn abuse of the dead as a form of symbolic disrespect. In rare cases, however, necrophiliac acts can be consensual: for example, in the Armin Meiwes case, the victim gave his consent to the mutilation and death inflicted upon him.
