I went through the south vegas ruins and the area around Cook-Cooks hangout killing fiends by droves
and I didnt' get zilch in the way of karma. Just to be sure, I unloaded all my mods, started a game over fresh
and went back to the same area, again with the same results.

For a certainty I was getting good karma for kiling them a few weeks ago. It just doesn't make
any sense. What have to got to do to gain karma points for killing them? I still get good karma
for snuffing NCRCF guys.

It seems counter-intuitive that you get karma for killing anything. You would think that killing a bad guy would even out instead of giving karma for kills.

speculation aside, your supposed to get good karma for killing fiends.

Maybe they are spawn by the quest?, maybe they used different code as normal fiends, and dev. might have left off.

I hated how fiends give you good karma. Its annoying because a lot of enimies give you good karma when you kill them and it makes it hardd to be a neutral or evil character when every "evil" enemy attacks you and gives you karma. It would be like having Feral ghouls giving you good karma in the subway in F3. In short, i wish m computer did thesame as yours.

Sry, having an OCD attack.
