Is, say, necrophilia ethically wrong? Arguably the ultimate societal taboo, necrophilia is something which the vast majority of people -- myself included -- consider disturbing and repulsive. It seems, however, that if we deem it morally objectionable we are left in a precarious situation, as we are forced to acknowledge that certain sexual behaviors without victims are wrong in and of themselves. If we accept this fact, what's to stop a person from deeming gay marriage wrong on the same grounds? Where could we possibly draw the line?
Having read some of the responses posted on this site, I have recently accepted the position that a person can be harmed even after their death. So, when I am speaking of necrophilia here, let's assume the person gave their consent before dying.
