It's not too odd that some people don't want to look at gore. For most of us corpses sterilize, become like objects the older they get, but I don't why that's anything but arbitrary.

Aboriginal Australians and Torres Strait Islanders get warnings that what they're about to view may contain depictions of people that have died. Not depictions of dead people, but depictions of people who have died since they were filmed or had their picture taken.
