As like a medical dissection? or just as a fucked up snuff thing? Because if it was for medical research then I really see no reason why it would be bad, as long as her family where okay with it and that it did not go against her death wishes or anything... Also, until fairly recently, like some time in 1900 we still used people that where sentenced to death for medical research, and in a way I think that could be horrible, but yet also kinda good, if they caused harm in society whilst alive, they can be at least be used for something productive and beneficial post-mortem, if that makes any sense at all.
