I was helping these two brothers get revenge for their father or something on this add-on for Morrowind called "The Helm Of Trohan." During the battle with the Daedra worshippers I accidently killed the brother who decided I should help them, so after the battle the other brother who didn't want me to help just stood there, looking depressed. I felt really bad.
Then I downloaded this other plug-in from Bethesda called "The Siege At Firemoth." I used it with one of my side characters, Lance, and went to lay siege to Fort Firemoth to kill a bunch of skeletons. Of course there were a lot more than I expected, and my entire backup team got killed while I ran away and stole a bunch of raw ebony. I actually felt bad later so I tried again on a different saved game and killed every single one of them.
