What did Carrie Fisher's on screen mom and her real life mom have in common? They both died from sadness.

Carrie's death was tragic and to a certain degree self-inflicted. She was a victim of herself, but that doesn't make it okay for you to marginalize her. Show your compassion for victims instead of using them for your jokes.
