Funfact: If you try and kill a pawn with deathward active via the Public Execution ritual from the ideology dlc, the game will just repeatedly try to kill the pawn (which, funfact, does not actually cause any injury in the process), it will do this until death ward runs out, at which point if your pawn would have died anyway, the execution gets cancelled, and if not, then the execution finishes as normal

Do note that your colonists' hunger and recreation will go down during this, so be sure to have a save ready if you feel goofy enough to try it
