It doesn't even have to include the slavers if you don't want it to. But some things, like the Red situation and the Marcella one, or the one I came across where I was in the Fairfax ruins and came up to a hut and two raiders attacked me. I killed the raiders and searched the hut to find a scavenger that they had killed. I searched the scavanger and got his things off his person, but then take a negative karma hit when I take things from his hut. Why? I mean he's dead, he's not gonna need them for anything, and I wasn't the one who killed him. If Ihad killed him then I can understand the negative hit to karma when I take his things but he was already dead when I showed up.
