Those who compare what is done or happens to humans with what is done to bodies should try to get their priorities in order. Look at the respective sentences for (mass) murder and what this man has done to see that society in general also sees a big difference in guilt. I have not the slightest difficulties to see why someone who wouldn't even dream to write a satire about torture or a mass murder feels alright with writing a satire about the crematorium theme.
