Most f'ed up quest?

Marked as spoiler since even though the quest is old as hell I just got done with it yesterday. Anyways just got done finishing mountain daughter quest. If you don't remember or know, the chief in some mountain village by relleka wants to leave the area but before that happens he wants you to find his daughter. Well turns out that his daughter was dead for over 10 years because a man dressed up and pretending to be some type of bear/animal god killed and ate her as well as several others.

In addition to this it turns out that the chief/dad/quest giver knew this all along but ignored it because he thought it was an actual god...which is crazy because gods do exist but most people/npcs to my knowledge are part of sects and don't kowtow to any random god even if it was real. Also, the daughter's supposed husband has been standing at the lake for I believe the same amount of time listening to her ghost sing/finding someone to help out her village to move along/get better.

Lots of quests feature kidnapping and murder, but I'm about 65-75% through the quests and I think to my knowledge this is the first time I've encountered a cannibal which surprised me the most, considering that I already figured her being dead was a strong possibility as soon as I started the quest.
