No. Maybe eating, if the person has nothing else to eat and is starving. I see necrophilia as extreme disrespect to the person the body once held, and if there's an afterlife, I'll also be aware of it. I think the question that will get real responses from people is, "could you watch either or both happening in front of you?" Some responses would probably be the same though. lol
Well you have to have different views for cannibalism since in some poor countries it is very common, but in MY opinion it is wrong for people who haven't had it in their culture. Necrophilia is wrong and gross, the thought of someone fucking a dead body is disgusting.
I...well it wouldn't bother ME, since I'd be dead. I'd be more concerned with it bothering people that care for me.
Though, for me personally, I want my corpse to go to a body farm so I don't think eating is really an option.
Cannibalism and necrophilia in general, well whatever. I don't have a problem with people eating other people. I don't really have a problem with people having sex with dead things, though it's not appealing to me. I don't think I'd want to sleep with someone who has sex with dead things, just because of the disease aspect.
