that whole storyline was a pretty good representation of what zersetsung targeted harassment is intended to do, or really any form of prolonged torture. the intent is to destroy the very foundations of the victim's personality, break down any and all resistance in their psyche, make sure they understand that they belong completely and totally to the willpower of the person holding them captive. there's no place in the world or even in their own mind that they can hold out any form of resistance, which is utterly and totally futile. at the end, the victim is totally depersonalized. nothing remains. they are a wreck of a person, not even worthy of being called human anymore.
