Makes sense, if you're into atheist utilitarian ethics. You're dead; you're useless; you're taking up space; cremating you would up your final carbon footprint and kill the rest of us off -- best to boil you in chemicals and flush you down the drain.
Instead of a pleasant trip to the local cemetery, you can make a visit to your local sewage disposal site.
Regain your humanity; rebel against the atheist machine.
And that's the way the Ball bounces.
