I've never thought about this. I'd want my account to go to my mom, and I think a few people might be affected online but not many because I'm kind of a loner on DA right now. Irl, I can think of about 13 people closest to me, including family and old/current friends. Of course, I've known more people than that, but 13 are the main ones that come to mind off the top of my head.
I would hope my death would start some awesome riot or memorial or something and everyone would be like "Live out your dreams.. for her! Heck yeah!" and the whole nation would be stirred up and suddenly everyone is so much happier because they're following what THEY want to do and not what society tells them they want to do.
My dream is a bit far fetched, but wouldn't that be simply epic? Also, if I knew it was coming I would design some pictures and put all my energy into them, for my watchers and friends and family irl and online and then put out a journal or something letting them know and how I know, etc. so they don't think it's a joke. I would put some words out for everyone I love, and maybe make a bucket list and do some crazy stuff like skydiving or going on scary roller coasters that I've never done because I was too afraid. Do all the things! Maybe even go traveling (if my family comes with me because that's a must have) and meet my own Flynn Rider (not a thief preferably), have a sad movie moment like "hey I'm going to die but first let's go to the egyptian pyramids or something before I keel over cause I'm going out awesome" and then after some tears I'd have an awesome death and everyone would remember what a cool life I had
Omg, this was so fun to write. This should be made into a movie, because there's definitely not enough awesome dying movies out there that both make you sob uncontrollably AND get off the couch to do awesome things because you're so inspired AND high five the TV because of how awesome I/the protagonist/whatever went out.
