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.
You can only be evil when you are alive. In death we are all rotting meat, neither good or evil.
Does rotten meat care about its burial at all?
Not entirely true, when memorials are built to an evil person which perpetuates their evil, that evil survives the mortal coil.
It’s why after taking DNA samples, Osama Bin Laden was thrown in the ocean, and Hitlers bunker was built over and his body disposed of by the KGB. Evil lives on.
