Ghosts can harm people, but they also see and can access all of time and all universes at any given moment. Dying is like losing your bookmark in a near-infinite book; it’s hard to get back to your place.

Paired with that, things we consider to be horrible atrocities of our time or past are blips compared to unfathomable things that have yet to come.

Ghosts do kill people all the time in other dimensions, and sometimes in ours, but it’s always ruled as something like a stroke or aneurism or whatever.

I don’t believe any of this but like to think of excuses as thought experiments and have been talking out of my ass.
