I mean, this question is not just about normal criminals.
Think like very bad crimes. Like serial killers, rapists, child rapists, terrorists, corrupt officials, terrible leaders, cruel dictators, generals that ignore laws of war, or like people has bad as Hitler. Which of these people do you think deserve a respectful burial, if any.
Is there a level of evilness that you think should not be allowed to have a proper buriel or have their corpses mutilated. Or should everyone deserve a respectful burial regardless of crimes.
I personally don’t even know how to answer this question myself. Like the funeral isn’t even for the dead. Its for the living. So to me, the question seems like, should the relatives of a bad person be allowed to see the corpse treated respectfully. I personally don’t have an answer to this question.
This is a question that is at least older than feudalism - the Greek tragedy Antigone deals with this question. And the answer, like always, is that desecrating a corpse is bad and dangerous and don’t do it, family is gonna be pissed and rightly so.
Even if it’s funny as shit that there were heads on sticks on top of Parliament for a while.
