Yeah to me that's the biggest objection... he's long dead, he has no surviving family that wants good for him to my knowledge. So to me that's kind of on the same level as, digging up mummies. The evil actions he commited in life don't really come into play here, and agreed it's really stupid idea to think that his behavior is genetic.

Kind of reminds me of when most of the nazi generals swore to have no kids to not carry on their DNA, except one, who said "No I won't sign that pledge, that's eugenics which is nazi ideology".
