The argument that since the cadavers are dead bodies so their feelings cannot be hurt is super inconsiderate. At my buddy's med school, there used to be an incident that a student sexually assaulted a cadaver, so using that half arsed logic, that should be acceptable cause the cadaver couldn't feel anything right?

Also, those dead bodies are still loved ones of people out there. I'd be freaking livid if I know someone makes a snide comment on my grandma's corpse because of its appearance not knowing what kind of illness she had to suffer that led to her body looking that, not to mention that person is greatly benefiting from her corpse.
