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.
The worst person in the world, while living, looses all consideration for how they’re treated. At that point, it’s not about what they deserve as much as it’s about living up to our own standards for how we compose ourselves.
We don’t feed evil people to rabid hogs not because they don’t deserve it, but because we respect ourselves more than that.
Likewise, everyone deserves a baseline level of dignity in death because that’s a standard we hold ourselves to.
It’s not for them.
