What kind of powers do we get?
This is a tough one. Part of me wants to go full dark vengeance on "bad people"TM, I would be like Light Yagami, I might go crazy with the power if I suddenly get to make life and death decisions about people that do bad things to other people. Expect pretty horrible things to happen.
Another part of me, would want to be a reaper of a different kind. I'd like to bring peace to people in this forum. If someone is trapped in a hopeless situation, and they want to ctb but can't, I would visit and help them. Give them a painless death. Kind of like scp-4999 but with a more active role in people's death. Although sitting with people that are dying and otherwise alone also sounds like something I'd like to take on as an eternal job.
Last part of me, would probably go to people I loved in life and just make beneficial things happen to them. Or maybe I would just haunt cats. At least cats can see ghosts, so I could look after cats that are lost or in need. Sounds busy, I think I'll defer cat ghost to someone else and take the scp-4999 job.
