The "Watson's Cabin" event in RDR2 is pretty fucked up...
Just finished it, you get the tip off about a cabin with some money in it from a guy that you save. First visit isn't very eventful, you meet a grumpy old lady. If you come back a couple days later, you end up in a shootout with her four sons and kill them all, and then (usually) kill the old lady too. I found that when I robbed the house I didn't find anything of enough value to make me feel like killing this entire family of innocents was worth it, up 'til now I've been able to justify all my actions as Arthur Morgan but right now I just feel like a straight up monster! I trespass onto this property and literally massacre this entire family for a few bucks, a rifle, and some canned vegetables.
Then you get to inspect the photograph on the desk and it's a picture of this woman standing proudly with her four sons, all of whom are currently bleeding out on the porch. Yeesh.
