Omg, I understand what you mean. All the angst we can shamelessly create without having a third party to judge us LOL. It's something you can't exactly do when you're writing professionally or for a wide audience, so it's a pretty damn good release, methinks. Plus we get to experiment more.
About writing off characters, it did traumatise me once, lol. When my RP partner and I were discussing plot for our next story, she would go, "Omg, he should die at the end." And I go, "No way bruh, I got a job interview in a couple of weeks. I gotta be emotionally stable LOL."
