Watcher from 1000XRESIST is tortured over several years in a sequence that's over an hour of game time. She goes through a lot.

Now that I've responded to the question and proven to the mods that this isn't a Deltarune thread, game theory:
> Kris was told to make the dark world in chapter 2 and leave the door open for the Knight.
> They were NOT told to slash Toriel's tires and get the police involved.
> That was to get Undyne involved, in the hopes she could stop the Knight.
> Tenna kept Toriel asleep because Kris told him to.
> Kris told him to so she wouldn't wander off and get caught by the Knight early.
Kris is a double agent.
