As I said her being dead means you can't now bully her. And there is a place for dark humor (though there are lines to be crossed).
Oh, I'm not bullying her, though I may offend people in the process of my joke. I just believe that the horrible things in life are also those that most desperately require guilty laughter. A little levity with your tragedy, so to speak. That, and I was ticked that people were getting offended at jokes, and conflating them with actually trashing this girl out of pure malice.
