@trinsec There's an episode of Red Dwarf about a time travelling executioner.
Perhaps it's an idea that's been floating around science fiction for a while.
@lydiaconwell Mm, I watched red dwarf but can't quite remember the time travelling executioner.
Though I'd be more interested in reading about the idea around it. Like, they have to send the executioner back to kill the culprit's grandfather just like they did in Oglaf. Wrong choices, implications, more killings as revenge 'YOU KILLED MY BLOODLINE BEFORE I *poof*' and such. It might be hilarious!
movie spoiler - Looper (2012)
@Pat @lydiaconwell Huh. I might have to see that.
